FORTRAN is generally the preferred spelling for discussions of versions of the language prior to the current one ("90"). Fortran is the spelling chosen by X3J3 and WG5. In this document a feeble effort has been made to capitalize accordingly (e.g. vast existing software ... FORTRAN vs. generic Fortran to mean all versions of the standard, and specifically the modern dialect, ISO 1539:1991). --------------------------------------- ~From: walt@fortran.com (Walt Brainerd) --------------------------------------- There was an effort to "standardize" on spelling of programming languages just after F77 became a standard. The rule: if you say the letters, it is all caps (APL); if you pronounce it as a word, it is not (Cobol, Fortran, Ada). See, for example the definitive article describing Fortran 77 in the Oct 1978 issue of the Comm. of the ACM. The timing was such that FORTRAN got put on the standard itself, though many always after that have referred to it as Fortran 77. Of course, there are those who think it is not truly Fortran if not written with all caps. ISO 1539:1991 and its ANSI counterpart X3.198-1992 consistently employ the spelling "Fortran" to refer to the language being defined. Reference(s) to the older version employ "small caps" for the "ORTRAN" characters. __________________________________________________________________________ 1.1.1) Where can I learn more about the history of Fortran? ------------------------------------------------- ~From: metcalf@apofort.cern.ch (Michael Metcalf ) ------------------------------------------------- The history of Fortran is documented in: Annals of History of Computing, 6, 1, January, 1984 (whole issue) Programming Systems and Languages (S. Rosen ed.), McGraw Hill, 1967, pp 29-47 (this is Backus's original paper) History of Prorammining Languages (R.L. Wexelblat ed.), Academic Press, 1981, pp 25-74 A summary appears in: Encyclopedia of Science and Technology, Academic Press, 1986, vol. 5, under 'Fortran' and in: Fortran 90 Explained (Oxford, 1990). Chapter 1 of __________________________________________________________________________ 1.1.2) How does Fortran 90 relate to FORTRAN '77? With a few minor exceptions, Fortran 90 is a superset of X3.9-1978 FORTRAN. But this does not mean that all "77" codes will port sans changes. Many (if not most) programmers employed constructs beyond the '77 standard, or rely on unspecified behavior (say, assuming that an OPEN of an existing file will position the file pointer to just past the last record already written) which has changed (that is to say, has become specified). This leads to the obvious question, what is new in Fortran 90? A complete answer would require considerable text. Some of the most obvious additions are: 1) array notation (operators, etc.) 2) dynamic memory allocation 3) derived types and operator overloading 4) keyword argument passing, INTENT (in, out, inout) 5) modules 6) modern control structures 7) free format source code form 8) other stuff While it is always tricky to characterize the motives of a large group of people, I am inclined to try as follows: '90 incorporates two sets of improvements: (1) relatively minor fixups that *could* have been done earlier (2) relatively major changes to enable better software engineering practices. Sometimes a "minor" fixup has major effect, such as addition of free form source form combined with canonization of the MIL-STD 1753 INCLUDE. I further go off on a limb and assert that it was the goal of the *committee* to evolve Fortran in a fashion to enable it to continue to be the premier language for scientific computation. __________________________________________________________________________ 1.1.3) Is it a Standard? Where can I get a copy of the Fortran 90 Standard? How about electronic copies? Fortran 90 was adopted as an International Standard by ISO in July, 1991. It was published by them as ISO/IEC 1539:1991, and is obtainable directly for 185 Swiss francs from: ISO Publications 1 rue de Varembe Case postale 56 CH-1211 Geneva 20 Switzerland Fax: + 41 22 734 10 79 or from: American National Standards Institute Attn: Customer Service 11 West 42nd Street New York, NY 10036 Phone: (212)642-4900 8:45-4:45 (EST) Fax: (212)302-1286 BSI 2 Park Street London W1A 2BS DIN Burggrafenstrasse 6 Postfach 1107 D-1000 Berlin 30 AFNOR Tour Europe Cedex 7 92049 Paris La Defence SCC 1200-45 O'Connor Ottawa Ontario K1P 6N7 You can obtain copies for $225 through: Global Engineering Documents 2805 McGaw Ave. Irvine, CA. 92714 (714) 261-1455 (800) 854-7179 In accordance with an official agreement with the International Standards Organization, Unicomp is now able to distribute electronic versions of the Fortran 90 standard: ISO/IEC 1539 : 1991, Information technology--Programming languages--Fortran The money received from this effort will go partly to fund ISO activities and partly to recover the costs incurred by Unicomp in preparing and typesetting the standard document. The prices are set by ISO. The document can be obtained in three versions: 1. An ASCII version suitable for viewing on a computer terminal using any kind of editor. Cost: USD 125. 2. A PostScript version with a license allowing the purchaser to print n paper copies. Cost: USD 125 + 10n. 3. Complete source in ditroff with macros and software to extract and create the annexes. The source constitutes a fairly high level marked-up document; for example, each program beginning and ending is marked and there are few low-level typographic commands such as size and font changes. Cost USD 1000. I am quite enthused especially about version (2). If you want to have 10 copies for your organization, and it costs $10 to make a printed copy, then the cost to make the 10 copies would be $125 + $200, or just $32.50 per copy, which is a substantial savings over purchasing paper copies. Versions (1) and (3) will be accompanied by a license restricting use to one CPU and prohibiting copying, except for backup purposes, etc. The version (2) license will prohibit distributing any of the printed copies outside of the purchasing organization. If you have special requirements, such as wanting to distribute a copy with each version of your compiler or using the source as a part of your documentation, we can make special arrangements, subject to the approval of the ISO. Please advise me of your requirements and we can work up a proposal together. ISO and Unicomp think this will provide the oft requested access to the standard in electronic form. This is the first time this is being tried, so we hope that organizations will be careful to observe the rules and encourage the continued availability of this and other standards in electronic form. Payment can be made by Visa or MasterCard, or with a check on a US Bank in US funds. We will accept a purchase order only if the amount is $500 or more. Walter S.

Typically X3J3. X3J3 is an ANSI subcommittee dedicated to Fortran. WG5 is the ISO counterpart. WG5 owns responsibility for Fortran on an international basis. WG5 has previously tasked X3J3 to do the work. This arrangement continues. WG5 is composed of Fortran users, vendors, and academics from several ISO supporting nations. Delegates represent *their*countries* not their companies; so several delegates from a single company is permitted. ANSI rules prohibit multiple voting delegates from the same company. X3J3 is composed of users (aerospace, government labs, military, DECUS, railroads, oil to name a few), vendors (IBM, CRI, Sun, Convex, DEC, UNISYS, to name a few) and the odd academic (oxford, yale, liverpool, to name a couple). Members need not be US citizens nor must their company be US domiciled. Being a member of a standards group is typically involves non-trivial work. To be effective, one should plan on at least 8 weeks of time per year (those who are really doing the hard work do far more). This time commitment is typically far more expensive than the travel and membership costs. X3J3 meetings are open to the public. There are typically 4 meetings a year, typically 3 are in the US and 1 *may* be overseas (to precede or follow the WG5 plenary session). Membership fees are levied by ANSI, and are on the near order of $600 ($300ish cast as an ISO "tax", but mandatory for all). In addition, attendees to a particular X3J3 meeting pay a "meeting fee" which covers reproduction costs, snacks and etc. The meeting fee has been about $100 for the last several meetings. WG5 has established various goals and targets for future work. Roughly speaking 5yrs rather than 13years are the targets for future work. Current work projects include cleanup and interpretations of Fortran (90), features for future versions of the standard (e.g. parallel processing, "object-oriented" technologies, etc.). In addition to work done directly by X3J3, there is work on standardized modules, and OS bindings taking place in other organizations. X3J3 would like to keep track of such efforts, those involved are invited to inform X3J3 early in their development efforts if possible. X3J3 is currently working with X3H5, DIN (varying string character) and tracking the efforts of HPFF. New members are always welcome. Visitors are also; though it is very hard to get a good grip on things in only one meeting! Contact the X3J3 chair for more information: email: jwagener@trc.amoco.com (chair) Upcoming meeting is: 5 Feb - 9 Feb Las Vegas papers are often available via ftp from: host: ftp.ncsa.uiuc.edu directory: x3j3 __________________________________________________________________________ B) Learning Fortran 1.2.1) What are good books on Fortran?

One is F: Announcing the first book on the F programming language ------------------------------------------------------- "The F programming Language", by Michael Metcalf and John Reid, Oxford University Press, Oxford and New York, 1996, ISBN 0-19-850026-2, (about $US30 or 16.95 pounds sterling). The F programming language is a dramatic new development in scientific programming. Building on the well-established strengths of the Fortran family of languages, it is carefully crafted to be both safe and regular, whilst retaining the enormously powerful numerical capabilities of its parent language, Fortran 90, as well as its data abstraction capability. Thus, an array syntax becomes available as part of a medium-size, widely-available language for the first time. In this respect, the language is clearly superior to older ones such as Pascal, C, and Basic. F is ideally suited for teaching as a first programming language, and provides a smooth path into both Fortran 90 and High Performance Fortran (it is a subset of both). In the absence of a formal standard for F, this book is the defining document for the language, setting out the complete syntax and semantics of the language in a readable but thorough way. It is essential reading for all F practitioners. Compilers for F are available from Imagine1 for Windows 95, Linux and some Unix platforms, with Windows NT, Macintosh PowerPC and 68K families coming shortly. The compilers are based on technology from Absoft, Fujitsu, and NAG. For details see: http://www.imagine1.com/imagine1 or contact info@imagine1.com. Table of Contents: 1.

Also on offer is elf90, a subset language that does not have old features like storage association, is designed for teaching, and is very cheap. Also "Prof. Loren Meissner" can provide information, and possibly a textbook on this dialect. But in a nutshell, elf90 is said to be f90 sans What's not in Elf90 To promote a more efficient and modern programming language the Fortran statements listed below are not supported by the Elf90 language. If you use a Fortran 90 feature that is not supported, an on-screen error message is provided.

Addresses 1.0 Fortran 90 and Fortran 77: ------------------------------ Fortran 90 is, with very few exceptions, a superset of Fortran 77. The FAQ of the Usenet group Comp.lang.fortran deals with both standards, and may be obtained, like any FAQ, via anonymous ftp from: ftp://rtfm.mit.edu/pub/usenet/comp.lang.fortran/Fortran_FAQ host: rtfm.mit.edu directory: pub/usenet/comp.lang.fortran file: Fortran_FAQ It is also available on the WWW: http://www.cis.ohio-state.edu/hypertext/faq/usenet/ fortran-faq/faq.html The present document is an attempt to supplement that FAQ with some specific Fortran 90 information. Anyone interested is also invited to join the mailbase list comp-fortran-90, by sending an e-mail message to: mailbase@mailbase.ac.uk containing the only line: join comp-fortran-90 firstname lastname more info on URL: http://www.mailbase.ac.uk/lists-a-e/comp-fortran-90/ The main extensions of Fortran 90 over Fortran 77 are: ------------------------------------------------------ o array notation (for instance, X(1:N)=R(1:N)*COS(A(1:N))) o dynamic memory allocation (ALLOCATE, DEALLOCATE, ...) o derived types and operator overloading o better declarations, and prototyping possible o MODULES, allowing users to create ``storage pools'', or to define environment o more of modern control structures (SELECT CASE, EXIT, ...) o more of useful intrinsics (date, precision, arrays, ...) o free format source code form ``Pure'' Fortran 77 is F90 compatible. Yet, it is better to convert it to a ``mixed'' format, acceptable both as free and fixed source form Fortran 90, which only requires replacing C by ! as the comment character, to use & as the continuation line character, and to append it to the continued line, to remove blanks embedded inside constants or identifiers, and to check some intrinsics usage. Most of this can be done automatically. Fortran 90 allows the Fortran 77 programmer to write code faster, to make it more legible, and to avoid many bugs. For a newcomer to programming, it is an opportunity to learn a modern language, with most recommended features, and yet to be in line with scientific and industrial engineering communities where Fortran is and is going to remain for a good while THE favourite language. 2.0 Available in Fortran 90: ---------------------------- 2.1 Compilers ------------- There is presently no free full F90 compiler.

Prentice appeared in the May/June 93 issue of Fortran Journal. He also gave a new one in the Nov/Dec 94 issue. I made some tests myself with LAPACK, and got a ratio of 10 between Sun f77 and Nag f90 2.0 when no source change was performed. With an aggressive rewriting, especially using array instructions and intrinsics, the ratio gets down to 2, which is also that of a f77 [sd]axpy to a C one. On actual applications, this ratio seems to be much closer to 1, and even sometimes in favor of Fortran 90. On Sept. 7th, 1993, John wrote "I think there is in fact beginning to be a quite large body of evidence to suggest that most of the efficiency fears about F90 are unfounded." For Nag f90 on workstations, the effect of the underlying C compiler (gcc, vendor, etc...) seems very limited (less than 4%). With more recent F90 compilers, performance seems at least as good and often better than with the corresponding F77 compiler, for old F77 code. For instance, Lahey reports improvement from 8.5 to 14.1 Mflops with linpack on a pentium between EM/32 and their F90 compiler. 5.0 Announced, foreseen, and rumours ------------------------------------ F: a carefully crafted subset of Fortran 90, meant for both teachers and professional programmers, by Imagine1 Inc., NAG Inc., Fujitsu Limited, and Absoft Corp. F will be available on Unix and Linux platforms, the 68k or PowerPC Macintosh, and PCs running either Windows 95 or Windows NT. FORTNER Research (formerly Laguage Systems Corp) expects to deliver f90 for Macintoshes in 1996.

A new release is scheduled for 1996 (called 95), mainly devoted to clarifications, corrections and interpretations. It is currently being circulated as a draft for comments. A more important revision is scheduled for 2000 (or 2001 ? called F2k though C.Burley's F00 is a pleasant alternative). Some interim features are to be processed as "technical reports" and incorporated in the next major upgrade, now known as "Fortran 2000" and planned for release around the year 2000. The features for which interim technical reports have been proposed are the following: o Floating-point exception handling o Interoperability with C o Parammeterized derived types and allocatable components However, the last of these lacks support in some quarters. The ISO working group devoted to the evolution of Fortran is WG5. URL: http://www.etrc.ox.ac.uk/wg5.html Inputs are received from the National bodies (X3J3 in the USA). Documents related to the work of X3J3 can be found via anonymous ftp on ftp.ncsa.uiuc.edu, directory x3j3. 7.2 - HPF --------- High Performance Fortran (HPF) is a language for programming massively parallel architectures.

Our goal is nothing short of providing one place to find all information, products, and services related to Fortran. The URLs are: http://www.fortran.com/fortran/market.html http://www.fortran.com/walt/fortran The Market is under construction (and probably always will be), but there is already some free software available (just some simple, but perhaps useful, things so far). There are pointers to other locations containing relevant information, so you now need to remember only one place to find it all. Much more information, particularly about products and servies will be available in the near future, but I thought you might want to have a Sneak Preview of what things will look like. Come visit the Market and let me know what you think of it. Thanks. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 2.1) Compilers and preprocessors 2.1.1) Where can I get a free (FORTRAN 77) compiler? There are few such in wide distribution: o f2c + any C compiler o f2c combined with djgpp o A combination of (f2cx + gcc + djgpp extender) o GNU's g77 o BC-F77 ;; One such is f2c: ----------------------------------------- ~From: mwm@a.gp.cs.cmu.edu (Mark Maimone) ----------------------------------------- Since there have been several requests for a Fortran to C translator in the past week, I'm reposting the announcement about f2c. The short answer is you can get f2c by anonymous ftp from: host: netlib.att.com directory: dist/f2c. ----------------------------------------------------------------- Source for f2c, a Fortran 77 to C translator jointly developed by folks from Bell Labs, Bellcore, and Carnegie Mellon, is now freely available. F2c was derived from the original UNIX operating system's f77(1), and the generated C follows f77's calling conventions; on some machines, the resulting object files are interchangeable with (and behave indistinguishably from) objects compiled by f77. The main "advantage" of f2c is that it converts ANSI standard Fortran 77 into C without manual intervention, at least when invoked by a suitable script or makefile (that may need to exercise an f2c option to ensure that COMMON blocks are defined just once). The main "problems" are that f2c does no code restructuring (e.g., gotos are preserved) and that Fortran I/O gets converted into a bunch of calls; thus the translated C code doesn't look too pretty, and in general one would need to maintain the Fortran rather than its translation into C. [F2c is not meant to displace the services of commercial vendors whose business is to convert Fortran into maintainable C.] There is a plethora of options, many of which exist to support different compilation environments for the translated C (e.g., ANSI C or C++ compatibility, different type sizes, separate files for COMMON blocks to appease "smart" linkers). So far f2c (and f2c-generated source) has compiled successfully on many machines: Sun, Vax, IBMRT, Apollo, SGI, MIPS, and Cray to name a few. F2c has been under test by the net community for over a year and has been verified on the NBS tests, several large math libraries, floating point tests, even code for laying cable on the ocean floor! To find out about f2c, send the following E-mail message to netlib (netlib@research.att.com or research!netlib): send index from f2c Your message will be answered automatically (by a program -- see CACM vol. 30 #5 (May, 1987), pp. 403-407). You will receive a reply explaining how to automatically acquire f2c source (about 600K), f2c library source (130K), and supporting info (man page, etc). Or you can anonymous-FTP to: research.att.com and look in directory dist/f2c at these files: all.Z -- 250K compressed shar file for f2c f2c.ps.Z -- 24 page tech report describing f2c index -- general info about files libf77.Z, libi77.Z -- compressed shar files for libraries ****************************** DISCLAIMER ****************************** Careful! Anything free comes with no guarantee. --- Mark Maimone phone: (412) 268 - 7698 Carnegie Mellon Computer Science email: mwm@cs.cmu.edu cmcspt!mwm@cs.cmu.edu Notes: f2c accepts only fairly vanilla FORTRAN; vendor supplied f77's usually produce better quality code, and accept a wider variety of codes. More about f2c from Judah Milgram --------------------------------- I recently asked about running f2c with djgpp. Turns out to be easy and together they make a good Fortran compiler for PC's. Here's a summary. I started with f2c dated Nov. 1994 (netlib.att.com in netlib/f2c). djgpp was v. 1.12 (omnigate.clarkson.edu in pub/msdos/djgpp.) Use the pre-compiled msdos f2c executable that comes with the f2c release. Compile the libraries with djgpp, making the changes listed below. They aren't necessarily the most sensible changes, but they worked for me. Write if you have a better idea. Thanks to all net people who helped, especially Dr. James Lupo.

Or, do 'coff2exe foo' to produce a .exe file which you can run in the usual manner. --------------------------------------------- ~From: Greg Lindahl --------------------------------------------- f2c is quite free. A ready to use package (F2CX + GCC + DJGPP) from Clive Page: I have packaged up a free Fortran77 system for MS-DOS into two files which are each just under 1.4 MB (to fit on 2 floppy disks). This isn't actually a compiler but relies on the F2CX translator to convert Fortran77 into C, and then GNU's GCC compiler plus the DOS-extender of DJGPP to get a flat 32-bit address space on MS-DOS. This sounds awkward to use, but works surprisingly well on most Fortran code that I have used. Warning: this is free software, no warranties at all, but it works for me and some of my colleagues also say it works for them. The files are available by anonymous FTP from: host: ftp.star.le.ac.uk in directory: pub/fortran files: ff77.tex Instructions for installation and use, Latex format (22k) ff77.ps Ditto, but in Postscript (99k) ff77.000 First binary file (1.4 MB) ff77.001 Second binary file (1.1 MB) tar.exe DOS version of Unix TAR, needed to extract s/w (52k) Transfer the ff77.tex (or .ps) file in ASCII mode, the others need BINARY mode.

Unfortunately I think that the info in this section is somewhat rather old. I would encourage you to make additions regarding the availibility of g77: 1. g77 is now at version 0.5.18, it should be used with gcc-2.7.2, because of some improvements in both. It works quite stable and allows (in difference to f2c/gcc) the debugging at source code level (with gdb, newer versions). 2. There are binaries in many linux-distributions, so you are not required to compile it yourself (which is not too difficult, but some work) 3. Michael Holzapfel provided OS/2 binaries using the emx-port of gcc. He wrote, that he will try to keep them up-to-date for the next two years. These can be found for instance at: ftp.leo.org but many other os/2-mirrors carry them too, one might use archie. Because most students search a compiler for MS-DOS, I want to emphasize, that these are running fine under DOS and take advantage of all available memory. With the additional rsx-package they run also with win3.1, win/nt and win95. 4. I tried the recommended bcf for DOS some time ago and was not able to run any fortran code. (maybe I'm stupid) The system seems to be mainly for teaching fortran and is rather limited. Anyone who wants to compile and run real applications should g77 give a try, it's worth every cent. BC-F77: ------------------------------------------ ~from: Kurt Jaeger pi@rus.uni-stuttgart.de ------------------------------------------ Someone asked for a cheap MS-DOS Fortran compiler for students.

Fortran90 is an ANSI and an ISO standard. The usual reference is Fortran 90 Handbook, published by McGraw Hill. Several vendors provide Fortran 90 translators and/or compilers. HPF --- High Performance Fortran (HPF) is a language for programming massively parallel architectures. It lets the user insert directives for code and data distribution among the processors in the (Fortran 90) code. Electronic copies of HPF draft specification are available by anonymous FTP from the following sources: Machine name File name ----------------- ----------------------------------- titan.cs.rice.edu public/HPFF/draft/hpf-v10-final.tar titan.cs.rice.edu public/HPFF/draft/hpf-v10-final.tar.Z titan.cs.rice.edu public/HPFF/draft/hpf-v10-final.ps titan.cs.rice.edu public/HPFF/draft/hpf-v10-final.ps.Z think.com public/HPFF/hpf-v10-final.ps.Z ftp.gmd.de hpf-europe/hpf-v10-final.ps.Z theory.tc.cornell.edu pub/hpf-v10-final.ps.Z minerva.npac.syr.edu public/hpf-v10-final.tar.Z Fortran D is a precursor to HPF; as a commercial product it has been superceded by HPF, but several academic projects still exist that target Fortran D. PVM is a message passing library and run-time environment; as such, it exists at a lower level than the previous items. One might imagine an HPF processor that produced FORTRAN77 with calls to PVM. There is a newsgroup on PVM. It is available through netlib, and possibly from Oak Ridge as well. Hope this helps. -- Larry Meadows The Portland Group lfm@pgroup.com ---------------------------------------- From: gale@hpc.pko.dec.com (Israel Gale) ---------------------------------------- Keith, Here is a suggestion for your "Parallel Fortran dialects" question (Q30) (2.1.5) on your (very useful) Fortran FAQ. Larry Meadows' information on HPF is largely correct (except for his saying "massively" parallel -- massively parallel is the one major parallel architecture for which HPF is not yet available), but I thought I'd contribute a few words about compiler availability: High Performance Fortran (HPF) is an extended version of Fortran 90 for parallel programming. It lets the user insert directives into Fortran 90 code which specify the distribution of data across processors. Currently, most HPF products are not true compilers, but source-to-source translators. Source-to-source translators are pre-processors that translate HPF code so that it can be compiled by a compiler without native HPF capability. They typically output FORTRAN77 source code, with calls to a message-passing library such as PVM or MPI. Compilers, on the other hand, produce object modules containing calls to either a standard message-passing library like PVM or MPI (as in the PREPARE compiler currently under development in Europe), or to a customized message-passing environment (as in Digital's HPF compiler). As of May, 1995, the following vendors offered HPF products: Compilers Source-to-Source Translators -------------------------------- ----------------------------- *Digital Applied Parallel Research Hitachi Intel Kuck and Associates Meiko Motorola NA Software NEC Pacific Sierra Research *PGI SofTech The first versions of HPF offered a partial implementation known as "Subset HPF". Beginning in 1995, a small number of vendors began offering implementations of the full HPF specification. Currently, only the vendors marked with an asterisk (*) offer full HPF support; all the others support Subset HPF. The runtime performance of HPF codes varies widely from vendor to vendor. The best-performing HPF products achieve performance comparable to hand-optimized PVM code. __________________________________________________________________________ 2.2) Other tools (pretty printers, lints, etc.) 2.2.1) I have heard of fortran "lints" what are they, and where can I get one?

Arguably worse, the compiler can produce any result it deems fit, up to and including the start of world war III (assuming the right optional hardware has been installed). Fortran lint programs focus on searching out programming errors (or likely errors) and alerting the user. There are a wide variety of commercial and pd products.

There is a prettyprinter (called TIDY) available via FTP from the SimTel Software Repository (primary site oak.oakland.edu). It's in the directory SimTel/msdos/fortran (Note: the directory name SimTel is case sensitive.) Capsule review: does an ok job, sometimes has trouble with newer extensions (and even some Fortran 77 standard features). Not too bright about making good continuation-line break decisions. Free, and available via FTP, so probably the quickest solution. Includes source (in Fortran). 2. Greg Flint (afc@klaatu.cc.purdue.edu) at Purdue distributes a program called CLEAN77. Pretty good (higher quality than #1 above), also free, but must be obtained from Purdue (not available via FTP, not redistributable). Available for assorted systems: PC, UNIX, etc. In Fortran, comes with source. 3. There is an excellent prettyprinter in TOOLPACK - probably has more options than any other. Has trouble with extensions, such as long variable names. Free, comes in source form, in Fortran. TOOLPACK as a whole is pretty huge, and requires some work to install, but it might be worth it if you stick to pretty much standard Fortran. Distributed commercially for a fee by NAG, who may have a new, improved version that is better than the free one - I don't really know. Available via ftp (see archie for locations) 4. SPAG, formerly sold by OTG Systems (about $1000 for MS-DOS, more for Unix). Its main function is to restructure GOTOs into IF-THEN-ELSEs, but it also prettyprints. (I think they renamed this within the past year). plusFORT : a suite of tools for FORTRAN programmers : comprising SPAG, GXCHK, QMERGE, CMAKE and others.

TOOLPACK -------- ------------------------------------------------------------- ~From: "John D. McCalpin" ------------------------------------------------------------- Not too many people use it, but you might want to add TOOLPACK to the list of FORTRAN "lint" packages. Here is the blurb that I send to people who are interested: TOOLPACK is a large set of utilities written in FORTRAN to do FORTRAN code analysis and transformation. TOOLPACK begins by actually parsing the program with a fully FORTRAN- compliant parser and then does all the code transformations on the parse and comment trees. This means that you cannot confuse TOOLPACK by silly FORTRAN-isms that can easily overwhelm more naive utilities (such as ftnchek). For example, TOOLPACK correctly handles statements such as: D O U B L E P R E C I S I O N A(100,100) doubleprecision fred DO I = 1.2 READ(I,J) = 10. The usual interface to TOOLPACK is a set of 'csh' scripts that run the various TOOLPACK utilities to do specific tasks. The ones you will find most useful are: pol, polx, apt, dapt, decs, getlst, and discard. These are the prettyprinter, precision converter, declaration standardizer, and some necessary utilities. See below for more details. By aware that TOOLPACK is *very* rigorous about the FORTRAN-77 standard. You may or may not consider this an advantage. The scripts are described by the 'scripts' script, which delivers the following: ----------------------------------------------------------------- In the Toolpack script summaries below, the section numbers refer to the Unix environment Users' Guide where more detailed information can be found. To obtain on-line information about a script's usage, type its name without any arguments. FORTRAN Analysis Facilities getlst Produce a listing showing statement and token numbers. Report lexical scanning warnings and errors. (3.1.1) syn Report errors and warnings detected by lexical scanning, parsing, and examining a set of symbol attributes. (3.1.2) sem Report errors and warnings detected by lexical scanning, parsing, and examining an extended set of symbol attributes. (3.1.3) pfort Report errors and warnings detected by lexical scanning, parsing, examining an extended set of symbol attributes, checking for unsafe references, and checking conformance to a portable subset of FORTRAN. (3.1.4) statdoc In a user-supplied report template, place information derived from static analysis to assist in documenting the program. Examples of information the user may request are COMMON block usage, symbol attributes, and a graph of subprogram calls.

John.McCalpin@mvs.udel.edu NAGWare f77 Tools ----------------- The NAGWare f77 Tools are a development of Toolpack/1 that raises it from a public domain distribution service to a fully supported NAG product. Large parts of the software have been completely rewritten and considerable new functionality added, although all the old functionality of the analysis and transformational tools is still there. First released in 1991, the current version, Release 2 contains: nag_apt - Arithmetic precision transformation. nag_chname - Token based name changer. nag_decs - Declaration standardiser (can generify intrinsics). nag_fcalls - Call tree generator. nag_fxref - Variable cross-referencer. nag_libdoc - Interface lister. nag_lvi - Local variable initialiser. nag_metrics - Software metrics. nag_pfort - Portability verifier. nag_polish - Pretty printer. nag_polopt - Polish option file editor. nag_struct - Restructurer. nag_profile - Profiler and report generator. The tools are available for most Unix and VMS. These are just some of the many improvements and enhancements that we have made: 1. The US Military standard extensions (DO WHILE, ENDDO, IMPLICIT NONE, INCLUDE etc.) have been added to the familiar Toolpack/1 language definition, but analyser tools still report all extensions to the ANSI standard. 2. The tools have been substantially rewritten to increase the execution speed. Notably the lexer and parser have been 100% rewritten to operate faster and give very much better error messages and error recovery. 3. The user interfaces for the tools are integrated well with the target operating systems. Access is via Unix scripts (or VMS command language) that carry out complete tasks. e.g. To invoke the Portability Verifier for a mixture of Fortran and Attribute files, with lower case character warnings suppressed: Unix nag_pfort -nolcwarn a*.f b*.atr VAX/VMS nag_pfort/nolcwarn a*.for,b*.atr The script calls the semantic analyser for the Fortran files and passes the Attribute files straight to the Portability Verifier. Or, to call the Precision Transform and Declaration Standardise in one step: Unix nag_apt -decs file.f VAX/VMS nag_apt/decs file.for 4. User oriented documentation is based around the scripts. A relatively slim volume provides all the necessary information to run the tools. A step by step introduction to each of the tools is provided, with small examples. 5. The portability verifier has switches that allow groups of less serious messages to be suppressed. For example, all warnings about use of non standard characters in strings can be switched off. 6. The portability verifier can dump its internal tables to a "library file" that can be loaded in a subsequent pfort run. This can be used to provide a definition of argument passage in a subroutine library to check a program that calls the subroutine library. Library files are more compact and more efficient than attribute files for this purpose. 7. Include files are dealt with sensibly by default, the lexer knows about the MIL-STD INCLUDE statement and merges include files. The polisher, by default, un-includes the included text. Nag_decs, again by default, does not declare variables declared in include files. 8. Tools are distributed in executable form only. The installation task is therefore minimal. We are developing a new option to the Portability Verifier to aid in porting to Fortran 90 by allowing Mil. Std. extensions, names up to 31 characters, etc, without the usual errors/warnings. NAGWare f90 Tools ----------------- These tools make use of the front-end of the NAGWare f90 compiler. Currently, only a small suite of tools is offered, but development is on-going. Fixed format input is acceptable, but all output is free format. Release 2.1 contents are: - Pretty printer (polish) - Declaration standardiser - Precision standardiser (Standardises precision of REAL and COMPLEX) - Name changer - Call Graph Generator - Dependency Analyser (Generates Makefile dependencies) - Interface Block Builder - Use Statement Annotator (Adds an ONLY list to USE statements listing imports) Also a module builder and polish options editor are provided. Release 2.1 has a full Graphical User Interface as well as a command line interface. Availability: Most Unix (now). Best regards and many thanks, Ian.

Dave Appel Hindsight/Fortran Summary: Features include the ability to draw an interactive structure chart and display coverage, software complexity and performance information on the structure chart.

As for the more general question, what is WEB .... WEB is a "literate" programming system created by Knuth (he of reference book fame, and TeX fame, and etc.). It permits the programmer to write code and documentation together. WEB takes the "high level code and documentation" and creates real publishable documentation (using TeX or LaTeX) and compilable code. WEB versions for many languages are available. Some features of FWEB are: 1) FWEB is a pretty printer. Code is pretty printed by sending the FWEB file through "fweave" and "TeX". fweave inserts TeX control characters around the code for pretty printing. Fweave also collects a cross-referenced index of *all* identifiers and prints them at the end of the code listing. 2) FWEB has built in macro preprocessing, which *does* understand FORTRAN syntax and code layout rules. A line extending beyond column 72 will be broken into proper continuation lines. 3) FWEB is multilingual: it understands C,C++,f77,f90, and RatFor. __________________________________________________________________________ 2.2.4) Fortran text editors?

Source code conversion program from ftp --------------------------------------- Many people who start to code in Fortran 90 prefer to do so using the new, less restictive, source form. However, a problem arises when wanting to modify old FORTRAN 77 code while sticking to the new style. To help in this situation, a source code conversion program has been written (and well tested) and made availble by anonymous ftp. Apart from the conversion, the program can: o ensure that blanks are used correctly in the code as they are significant with the new source form; o indent DO-loops and IF-blocks; o replace CONTINUE by END DO, where appropriate; o add subprogram names to END statements; o change non-standard length specification syntax, like INTEGER*2, to the Fortran 90 equivalent, in all contexts (type statements, FUNCTION statements, and IMPLICIT statements); o produce an interface block automatically from the source code of a procedure - useful to the library developer when wishing to use this important new facility with an existing library. The source code can be obtained by anonymous ftp to: jkr.cc.rl.ac.uk (130.246.8.23) When prompted for a userid, reply with: anonymous and give your name as password. The directory is /pub/MandR and the file name is convert.f90. Mike Metcalf (metcalf@cernvm.cern.ch) __________________________________________________________________________ 2.2.6) What is preprocessing, how can it help? How can it hurt? Preprocessing often refers to usage of a Macro-prepressor upon ones source code prior to compilation. How can this help? It can make it easier to move code between machines. How can this hurt? It can cause difficulties in compilation of the processed code; most (if not all) macro-preprocessors know nothing about Fortran syntax and code layout rules. So, a common problem is that after preprocessing some text may be lost past "sacred" column 72. Those working with compilers that optionally compile *past* line 72 should probably employ that option when using a preprocessor. Common prepressors are: cpp, m4, and ratfor. Many sites have their own custom prepressors. Basic functions are: 1) definition of a symbol 2) conditional code selection based on a symbol 3) substition of a symbol by its definition Traditional BSD Unix f77 processors treat a file named foo.F (as opposed to foo.f) as one that should be run through cpp prior to compilation "automatically". 2.3) Fortran Packages and libraries 2.3.1) Where can I get "foo" (some random package), older posts to comp.lang.fortran etc ---------------------------------------------------------- ~From: mroussel@alchemy.chem.utoronto.ca (Marc R.

Archie can be used either via telnet or by mail. For information about archie send mail to: archie@archie.rutgers.edu subject: help And you will get back copious directions on how to use archie. If you prefer interactive experimentation, telnet to: archie.rutgers.edu and log in as archie. No password will be required. The first thing you will be shown is a list of other archie servers. If one of these servers is geographically much closer to you than Rutgers, NJ, please disconnect (by typing 'quit') and use that one. To save you this step, here is a list of archie sites: archie.rutgers.edu 128.6.18.15 (Rutgers University) archie.unl.edu 129.93.1.14 (University of Nebraska in Lincoln) archie.sura.net 128.167.254.179 (SURAnet archie server) archie.ans.net 147.225.1.2 (ANS archie server) archie.au 139.130.4.6 (Australian server) archie.funet.fi 128.214.6.100 (European server in Finland) archie.doc.ic.ac.uk 146.169.11.3 (UK/England server) archie.cs.huji.ac.il 132.65.6.15 (Israel server) archie.wide.ad.jp 133.4.3.6 (Japanese server) I believe that all of these servers run the mail server as well as the telnet and archie server software. (The archie server is a third way to use archie. It's probably the best way, but it requires that you install software.) Once you logged into an archie server, you will want to make sure that all the information you will retrieve will be mailed to you. Type: set mailto userid@machine.foo.edu where, of course, you will substitute your own email address for the made-up one shown above. You are now ready to search the database. If at any time you want to know what options are available to you, type help. To search for a program or file, type: prog foo where foo is the name of the program or file required. Once your search is done, type 'mail' to have the output sent to you. (The output will almost always be several pages long.)

The BLAS (basic linear algebra software) comes in several flavors: BLAS-1, -2, and -3. These can be described as scalar, vector and matrix-matrix levels. "Coded" BLAS are either hand coded in assembler, or at least tweaked for a given machine. Some vendors provide these, some are provided on the net (see archie) and some are marketed by various commercial organizations. In addition, it should be noted that BLAS-3 is very amenable to parallel processing. Done cleverly, this could be done by a network of processors over a net. DSS markets just such an implementation. Contact the folks below. The following material is their marketing blurb: DSSLIB is the fastest BLAS[123], LAPACK, LINPACK, FFTPACK, and VFFTPACK available for the entire SPARC hardware and software line. DSSLIB is based on LAPACK 2.0, but is backward compatible with all previous LAPACKs. Single-CPU optimization typically yields 2x-4x over Netlib code. MP computation yields significantly better than that, reaching almost half a gigaflop on a top-of-the-line Sun MP machine and exceeding even that on SPARC MP supercomputers. Interfaces are shipped with DSSLIB to allow users of IMSL/Math, Rogue Wave's math libraries, IDL from Research Systems, and others to optimize and parallelize their applications without making source code changes.

Freeware Date: Mon, 22 May 1995 19:39:41 Organization: Kansas State University Lines: 93 Message-ID: NNTP-Posting-Host: s20.slip.ksu.edu Keywords: FORTRAN Freeware X-Newsreader: Trumpet for Windows [Version 1.0 Rev A] Hello FORTRAN People, This is the first general announcement of the FORTRAN Library (FLIB). One of the unique aspects of this code repository is that a considerable amount of source code is available for non-numeric tasks, .e.g., string manipulation, time and date functions, conversion of numbers to strings (and vice versa), etc... Many of these tasks are among the most Frequently Asked Questions (FAQ) in the FORTRAN usenet group. The preferred (by me) method of accessing FLIB is through the World Wide Web. The information and code descriptions provided via the web will be more up-to-date and comprehensive, and it will be easier for you to maintain a stable link to this code repository if you access it via the uniform resource locator (URL): http://www.engg.ksu.edu/~robs/flib/flib.html FLIB can also be reached by generic file transfer protocol (ftp). If you have trouble accessing FLIB via your web client, try using a generic ftp program to access the anonymous ftp server at: godiva.ne.ksu.edu Login as anonymous and enter your email address (e.g., robs@ksu.ksu.edu) as the password. The flib files are under the directory ~pub/robs/flib. The current scope of the code in FLIB is summarized below. Please feel free to send me an email message describing your opinion/experience with FLIB (remember however that this is freeware). Rob Stewart robs@ksu.ksu.edu ------------------------------------------------------------ Scope of Code Repository The FLIB routines are currently divided into five areas: CharPak This package contains approximately 50 routines to manipulate character strings (e.g., upper to lowercase, removal of specific characters from a string, macro substitution). convert numbers to strings and vice versa, align/center text in specific columns, plus more... GeomPak For now this package contains less than 10 routines; basic routines are provided to scale, rotate, and translate points between coordinate systems. These routines are quite useful in a number of computer simulations involving 2 and 3-dimensional geometries -- including graphics. RanPak This package contains approximately 30 routines to generate random numbers sample from various probability density functions (pdf) including a disk, plate, box, sphere, and unit direction vectors from arbitrarily oriented cones (NOTE: some routines call routines from GeomPak). All of the algorithms for random number genration are based on the discussion of Lehmer generators (circa 1951) in the article Park, S.K. and Miller, K.W., Random number generators: good ones are hard to find. Communications of the ACM, 31, No 10 (Oct. 1988). TimPak A set of routines to access and manipulate the system time and date, compute the elapased time between two events, etc... Since most of these routines are system and compiler dependent, you will also need to select the appropriate file from the Compiler Abstraction Layer (CAL) -- see below. Compiler Abstraction Layer (CAL) A set of stubs or wrappers for widely used but non-portable and non-standard system calls or routines (e.g., system time and date). Rob Stewart robs@ksu.ksu.edu --or-- http://www.engg.ksu.edu/~robs/home.html Diplomacy: The art of saying "nice doggie" until you can find a rock. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 3.1) Fortran and other languages (Essentially C) 3.1.1) "Why do people use FORTRAN?, C is so much better" One should avoid such pointless arguments .... if you feel this way, don't subscribe to comp.lang.fortran. This sort of question always triggers off a protracted discussion, the highlights of which are typically: a) FORTRAN and C have different semantics. A FORTRAN optimizer knows more about aliasing, function interactions, and I/O. A C optimizer has to infer or compute such information. C bigots typically have neither written such optimizers nor worked with folks who do it for a living, and are prone to dismiss such arguments as being petty and neolithic. FORTRAN programmers are often a bit more in touch with high performance computing, and are unwilling to bet that heavily on compiler wizardry. In addition, ANSI C section 2.1.2.3 on Program Execution makes it clear that associative and commutative regrouping of operands is only allowed if it produces the same result as it would if the regrouping had not been done. Where it makes a difference is on hardware that produces an exception on arithmetic overflow, and the regrouping either causes or avoids an exception, that otherwise would not/would take place. In ANSI C a = a + 32760 + b MUST be evaluated as (a + 32760) + b NOT as a +(32760 + b) UNLESS the overflow exception will be the same in either case. Fortran is somewhat less tightly-buttoned about this, and allows the compiler-writer to regroup the expression and evaluate it in either order. Thus, in Fortran, whether you get an exception or not depends on the compiler, the level of optimization, and the hardware. In ANSI C, it only depends on the hardware. Of course, compiler options, vendor extensions and the like sometimes narrow the difference. Also, some Fortran compilers do not take advantage of all of these features of the language, thus narrowing the gap in the other direction. On any given code, on any given system, all bets are off. b) There is a vast body of existing FORTRAN code (much of which is publically available and of high quality). Numerical codes are particularly difficult to "vet", scientific establishments usually do not have large otherwise idle programming staffs, etc. so massive recoding into any new language is typically resisted quite strongly. c) Fortran tends to meet some of the needs of scientists better. Most notably, it has built in support for: - variable dimension array arguments in subroutines - a compiler-supported infix exponentiation operator which is generic with respect to both precision and type, *and* which is generally handled very efficiently or the commonly occuring special case floating-point**small-integer - complex arithmetic - generic-precision intrinsic functions d) Retraining staff is quite expensive. e) It is sometimes argued that: - Jonathan Thornburg Fortran tends to be easier for non-experts to learn than C, because its "mental model of the computer" is much simpler. For example, in Fortran the programmer can generally avoid learning about pointers and memory addresses, while these are essential in C. More generally, in Fortran the difference between (C notation) x, &x, and often even *x is basically hidden, while in C it's exposed. For non-experts this makes Fortran a considerably simpler language. Because of this relative simplicity, for simple programming tasks which fall within its domain, (say writing a simple least-squares fitting routine), Fortran generally requires much less computer science knowledge of the programmer than C does, and is thus much easier to use. An interesting (pro-Fortran 90) viewpoint on this subject from a practical point of view can be found at: http://www.hp.com/wsg/ssa/fortran/f90prent.html It's called "Fortran 90 as a language of choice for engineering students", and was written by Dr. John K. Prentice from Quetzal Computational Associates (Email: john@quetzalcoatl.com). __________________________________________________________________________ 3.1.2) Why are there aimless debates? There are some persistent individuals who would like computer systems to work in a fashion somewhat unlike they do now. It seems pointless to debate with them; the debates (in various groups) always take the same form and never result in meaningful dialog. One can usually recognize such by reading a week or so's worth of postings. Sometimes you may have to read for a month to recognize such. When you do, please try to avoid triggering (or responding to) such individuals. Many (if not most) newsreaders support a feature entitled KILL files. As you recognize individuals, you may wish to put them into your local kill file. For example, the style employed by GNUS: (gnus-kill "From" "dweeb@place.ISP") (gnus-kill "Subject" "test") the first kills off all postings from the named individual, the second kills off all postings including the beloved "test" string. See your local NewsGod for details suitable for your local system. __________________________________________________________________________ 3.1.3) How do I call f77 from C (and visa versa) This is quite platform dependent. For Suns see the FORTRAN User's Guide, Chapter 14. There is a package available from usenet which attempts to make this "quick and easy" for a wide range of platforms: Host ftp.germany.eu.net Location: /newsarchive/comp.sources.misc/volume20 DIRECTORY drwxr-xr-x 512 Jul 7 1993 cfortran Host ftp.sunet.se Location: /pub/usenet/comp.sources.misc/volume20 DIRECTORY drwxrwxr-x 512 May 28 1993 cfortran Host ftp.wustl.edu Location: /usenet/comp.sources.misc/volume20 DIRECTORY drwxr-xr-x 8192 Oct 30 15:09 cfortran Host halcyon.com Location: /dec/.0/usenet/comp.sources.misc/volume20 DIRECTORY dr-xr-xr-x 512 Jul 8 1993 cfortran Host lth.se Location: /pub/netnews/sources.misc/volume20 DIRECTORY drwxr-xr-x 512 Jun 7 1993 cfortran Host math.mps.ohio-state.edu Location: /pub/archives/comp.sources.misc/vol20 DIRECTORY drwxrwxr-x 512 Jun 2 1993 cfortran It is on many other sites (around the world) too. See archie if you need other pointers. For some systems, you have to initialize a runtime system explicitly if you call a different language, and stopping execution from the other program may not work.

Can anybody give : me some advice about how to do this? Hello, we have some programs written in C calling the NAG library (which is written in Fortran). There are a number of important things you must be aware of: 1) Fortran uses a column wise storage of matrices while C stores them row wise. This means that when you want to parse a matrix from your C-program to the NAG (-fortran-) routine you must transpose the matrix in your program before entering the routine. Of course, any output from such a routine must be transposed again. If you ommit this step, then probably your program will run (because it has data to compute on) but it will generate wrong answers. B.T.W. if you have the Fortran source code (of any routine) then on some platforms you may use compiler directives specifying that the Fortran compiler must use row wise storage. Some platforms support these directives. However watch out with this if you call the same routine from another Fortran routine/program. 2) Your Fortran compiler may add an underscore "_" to the routine name in the symbol table e.g. subroutine example(..,..,..) becomes example_ in the table. Hence in the calling C-program/routine you must add a trailing underscore ! Otherwise the loader will complain about an undefined symbol "example" while "example_" is loaded. However, check your compiler for this. For example the Fortran compiler on VAX-VMS systems does NOT add a trailing underscore (there watch out with the fact that the VAX-Fortran compiler translates everything in uppercase). 3) Fortran passes its variables by reference. This means that you MUST give adresses in your calling C-program (i know, this is a stupid remark but it is too often forgotten (my experience ....)). 4) Watch out especially with float's and double's. Make sure that the size of the variable in the calling program is identical to the size in the Fortran routine e.g. double <----> real*8, float <----> real This is extremely important on machines with little endian byte ordening. Parsing a float (C-routine) to a real*8 (Fortran) number will not generate SEGV but give wrong results as the data is parsed wrongly. 5) Remember that the array index in Fortran starts at 1 while in C this is at index 0; hence a parsed array fortran_array[1:100] must be used in the C-routine/program as c_array[0:99]. Good luck with it !! Rudi Vankemmel another post: --------------------------------------------------- ~From: beardsl@mepsi.mobil.com (Reginald Beardsley) --------------------------------------------------- I do a lot of this. The following is true on the following machines. I cannot say about others. Sun 3 & 4 IBM RS/6000 SGI DECstation Intergraph Clipper (Apogee & Green Hills compilers) H-P 7xx 1) If possible, do not pass strings to FORTRAN from C or vice versa. 2) Do not mix I/O on the same file descriptors. 3) Do all your math in FORTRAN, and all the rest in C if at all possible. 4) NEVER ever attempt to write the equivalent of a FORTRAN function that returns a character variable in C. Life is too short for the suffering it causes. 5) If you do ANY I/O in FORTRAN, you MUST use a FORTRAN mainprogram. 6) FORTRAN always passes pointers. 7) FORTRAN passes string lengths BY VALUE in the order the strings appear in the argument list. These do NOT appear in the FORTRAN argument list, but will appear in the C argument list. 8) You will need to take care of nulls and blanks spaces explicitly if you ignor 9) The Sun FORTRAN compiler used lex and yacc to do the conversion of a run time format from a character variable. If you use lex and yacc either rename the variables and functions or partially link before you link to the FORTRAN libraries. 10) FORTRAN symbols have trailing underscores appended. Some compilers require a compiler flag to get this. Use it! It makes the code more portable. 11) Don't pass structures. If you must access a structure element, pass a pointer through to a routine which passes back the element pointer. 12) Don't forget that the storage orders for arrays is opposite and transposition is expensive. I currently have many lines of code with FORTRAN calling C calling FORTRAN. It's not my choice of things to do, but it works well. Much better than using the wrong language for the task. My only regret is that I'm forced to pass a lot of strings between the two languages. Reginald H.

This can be advisable for reasons of clarity (i.e. keeping the documentation the code and the math in sync.) and for reasons of performance.

What tools are available? Regretably none. This is indeed unfortunate, as even a limited translator could help with typical C header files. __________________________________________________________________________ 3.2) Compiler and system differences 3.2.1) My compiler is mis-behaving; who enforces the standard? ANSI and ISO standards do not usually have a particular enforcement mechanism. Local bodies sometimes do. However, it should be borne in mind that if *your* source code is not standard compliant there is *NO* obligation for a FORTRAN ('77 and before) compiler to do *ANYTHING* in particular. In Fortran (90) the text in "constraints" must be tested and a warning produced (compiler option can be used to evade this, of course). Some (notably Guy Steele, with respect to another standard) have noted that when non-standard complying code is encountered, a compiler may do *ANYTHING* including initation of Global Warfare. Keep this in mind. When you do find a bona fide compiler bug, you are generally best served by reporting it to the *vendor*. If you neglect to tell the vendor, how can you complain about it not being fixed? When reporting a *suspected* bug be sure to be quite specific about the computer system, operating system rev level (patches applied if known) and *compiler*version* (and patches thereof). It is very hard for people to read your mind; but they will try. The attempts are often entertaining, sometimes helpful, but always an inefficient use of people-time and net-bandwidth. Also note that it is generally helpful if you cut down the example to the smallest size you can. Vendors are developers too; the tendency is invest time/money where one can get the biggest bang for the buck. __________________________________________________________________________ 3.2.2) My F77 program compiled ok on a , but gives me heaps of syntax errors on a . What's wrong? ------------------------------------------------ ~from: ecmtwhk@ccu1.aukuni.ac.nz (Thomas Koenig) ------------------------------------------------ Most likely, the program was written with a line length greater than 72. If your compiler supports it, turn on the option for greater line length (e.g. -e is not uncommon) ; otherwise, split up the lines by hand, or via one of those pretty-printers/restructing tools mentioned above. __________________________________________________________________________ 3.2.3) My F77 program ran ok on a , but on a , it just gives me strange results. What's wrong? ----------------------------------------------------- Original: ecmtwhk@ccu1.aukuni.ac.nz (Thomas Koenig) Revised by: klassen@sol.uvic.ca (Melvin Klassen) ----------------------------------------------------- There are different reasons why this could happen. Possibly, your program violates the standard in some way which is not caught by the compiler on , or in some way which the compiler on intentionally allowed, e.g., in FORTRAN 77, variable-names were restricted to 6 upper-case characters, while many compilers were extended to handle longer, mixed-case names. Some programs rely on the retention of values between invocations. Use SAVE statements for those variables which you need to keep across function calls. Some programs rely on variables to be initialized to zero when a subroutine or function is first called. Some compilers (VAX/VMS for example) exhibit this behaviour. Some operating systems (IBM's MVS/ESA and VM/ESA for example) have been observed to fill with a "zero" value the first time you reference a previously-unused area of virtual storage. Compilers on newer architectures often fill variables with garbage on each new function call. This is permitted, according to the standard. The solution is to explicitly initialize all variables. Your compiler may have an option to trap uninitialized variables; use that to find the trouble spots. For example, the IBM VS compiler will do a static-flow-analysis, and report such errors, when you specify the 'OPT(2)' option. Alternatively, if you are desperate, try to compile using a flag which forces static allocation of all variables. Another problem might be that the accuracy of REAL and DOUBLE PRECISION differs between different platforms; that can cause roundoff error to wipe out your results or your program to go into endless loops. Yet another (and much more subtle) problem can occur if a lot of formatted I/O is employed. The conversion from internal to external representations can introduce very significant errors; much worse on some platforms than others (doing correctly rounded base conversion is expensive). There are, of course, lots of other possibilities, these are just a starting point. __________________________________________________________________________ 3.2.4) How can I read my VAX binary data somewhere else? Some vendors provide bulit in methods (DEC provides this via special options on the OPEN statement). Others provide library support (on SPARC products, with the SunPro compilers, checkout convert_external) In addition, Accerl8 provides a commerial tool.

END DO It is very common; and of course is part of Fortran 90. Compilers claimed to *not* support it (much shorter list this way): 1) Salford ftn77/Primos version 2) Prime f77 compiler 3) Microsoft Fortran for CP/M 8080/Z80 machines 4) Fujitsu VPxxx UXP/M compiler __________________________________________________________________________ 3.3.2) What are ENCODE and DECODE statements, and how are they translated to standard Fortran? How can I convert numbers to character strings (and vice-versa)? ENCODE and DECODE are vendor extensions to Fortran (invented in the sixties, long before X3.9-1978 added internal I/O to the language) which are most often used to convert data between numeric and character representations. They may be viewed as formatted writes to (ENCODE) or reads from (DECODE) memory. The standard-conforming alternatives are internal write and internal read statements respectively. For example, INTEGER MONTH, DAY, YEAR MONTH = 7 DAY = 4 YEAR = 93 C FORM THE STRING 7/ 4/93 IN VARIABLE "DATE" ENCODE (8,10,DATE) MONTH,DAY,YEAR 10 FORMAT (I2,'/',I2,'/',I2) The above can be translated as "write 8 characters, formatted according to format 10, storing the results in variable DATE, and using the contents of variables MONTH, DAY, and YEAR as the data to write." A DECODE statement would be used to reverse the process (extract the variables MONTH2, DAY2, and YEAR2 from the string DATE). Thus: INTEGER MONTH2, DAY2, YEAR2 DECODE (8,20,DATE) MONTH2, DAY2, YEAR2 20 FORMAT (I2,1X,I2,1X,I2) Conversion of ENCODE/DECODE to standard Fortran-77 is not difficult. The critical thing to remember is that the variable to be written to (ENCODE) or read from (DECODE) must be a CHARACTER variable which is long enough to contain the string. The first number within the parentheses (in this case 8) is the minimum length to use in a type declaration. Thus a standard-conforming equivalent of the above example is: CHARACTER*8 DATE INTEGER MONTH, DAY, YEAR INTEGER MONTH2, DAY2, YEAR2 MONTH = 7 DAY = 4 YEAR = 93 WRITE (DATE,10) MONTH, DAY, YEAR 10 FORMAT (I2,'/',I2,'/',I2) READ (DATE,20) MONTH2, DAY2, YEAR2 20 FORMAT (I2,1X,I2,1X,I2) Although the above example used integers, any other data type may also be used. ----------------------------------------------------- From: ----------------------------------------------------- __________________________________________________________________________ 3.4.1) What is involved in parsing Fortran? ---------------------------------------- ~From: clodius@hotspec (William Clodius) ---------------------------------------- > I don't know if the following is any help > > Dec has published a discussion of some of the problems > in parsing Fortran > http://www.digital.com/.i/info/hpc/f90/loveman.txt > > There is a publicly available Fortran90 grammar for a compiler > generator at > > http://www.cs.colorado.edu/~eliuser/fortran_html/Scan.html > > The "compiler" generator that uses the grammar, ELI, > apparently has home pages at > > http://www.cs.colorado.edu/~eliuser/ > http://www.uni-paderborn.de/fachbereich/AG/agkastens/index_engl.html > http://coral.cs.jcu.edu.au/ > > however the links to Germany and Australia did not work > when I tried them out. > > The Sage++ compiler development system apparently has > Fortran 77/M parsers available > > http://www.extreme.indiana.edu/sage/index.html ------------------------------------------------ ~From: mjohnson@samson.tx.hac.com (Mark Johnson) ------------------------------------------------ > Christian Rutzinger wrote: > > >I want to write a Recursive Descent Parser for Fortran90. ,,, > > > >Am I wrong, or is (Standard) Fortran90 really a not > >LL(1) language? > > FORTRAN is definitely not LL(1).
