FORTRAN compilers on Pentium machines

Really depends on computer RAM and other applications you want to run: OS/2 2.1: Probabaly best if computer memory <=16Mb. Fortran apps can be run using the free GNU f2c fortran pre-processor and gcc compilers available using anonymous ftp to ftp-os2.nmsu.edu at New Mexico State Univ. OS/2 runs DOS, Win 3.1 and (of course, if you can find them) OS/2 apps very well. Windows NT 3.1 (1.0? :)) w/ service pack available at ftp.microsoft.com: Probably best if computer memory >=16Mb (a real memory buster). PowerStation Fortran from MS can make 32 bit apps, and some nmusers have been giving tips via this forum for several months (thanks alison!). GNU software as above is available on a CD from a company called Concurrent (I think). See topic 2 for discussion of Powerstation compiler options If you prefer a commercial Fortran compiler, I've had good luck with Microway products. They also make compilers for other Intel operating systems (DOS, Unix, etc). The only # I have is old, but should still work: (508)746-7341. Any one try to run NONMEM on a PowerMac yet? Bought one last week, and it is one fast son-of-a-gun.
