After 6 years of VMS systems it looks like I have a IBM R6000 coming in the near future. I would very much like to hear any comments about the quality of various fortrans available for it. The code I work with has avoided most of the VMS system calls, but things like long variable names, IMPLICIT NONE, include files and ENDDO sure are nice. I know next to nothing, though my IBM sales rep is going to send me some info on their product. However she says that the VMS extensions are not supported 8-(, though didn't know any details. Any sage advice out there? Chuck@MITLNS.MIT.EDU

Yes, the IBM RISC-6000 Fortran compiler supports most of the extensions you want. Among other things, Names up to 250 characters implicit none, implicit undefined (range) include 'source-file' in-line comments (! to EOL) double complex static, automatic do while, end do recursion (by compiler option) %VAL and %REF arguments --Pierre Asselin, R&D, Applied Magnetics Corp.
