1.0 Fortran 90/95 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 rtfm.mit.edu, directory /pub/usenet/comp.lang.fortran.

A specific Fortran 90 FAQ by Mike Metcalf may be reached at fortran.com.

The present document is an attempt to supplement these FAQs with some more links to Fortran 90/95 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:

The main extensions of Fortran 90 over Fortran 77 are:

``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.

Fortran 95 is a minor revision of Fortran 90. The 3 main extensions with respect to that previous version are:

2.0 Available in Fortran 90/95:


Free compilers are g95 and gfortran. Packaged gfortran can be obtained from François-Xavier Coudert If you agree with the conditions of their licence, and run Linux on an Intel machine, a free-for-non-commercial-use Fortran 95 compiler is available from Intel. The free f90 and HPF compiler for linux from Pacific Sierra is no longer available. Some compilers restricted to modern subsets of the language may yet be free, and better suited to educational purposes, such as F from The Fortran Company, now free for all platforms.

Information technology - Programming langages - Fortran Somewhat expensive (CHF 210 ~ US$ 140 !) for instance, at ISO. Surprisingly enough, the identical, save for foreword and acknowledgements, ANSI standard X3.198-1992 is even more expensive. Walter S. Brainerd, The Fortran Company., offers:

- for 125 US$, an electronic ascii monouser version,

- for 125 + 10n US$, an electronic PostScript version, and the right to make n paper copies,

- or for 1000 US$, an electronic ditroff monouser version.

4.- Fortran 90 Benchmarking

An interesting article by John K. 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

Fortner (LS Fortran) has exited the Fortran business on Mac (to concentrate on visualization tools). Per agreement with Fortner, Absoft is offering migration path from LS Fortran -> Absoft Pro Fortran. See: http://www.absoft.com/fortner.letter.html or contact dave@fortner.com for details

Absoft and Intel have signed deal to evolve Absoft Fortran toolsets for IA/NT.
