Fortran?

Does anyone know where to get Fortran for a hobbyist IA64 system?

(Is anyone here actually using Fortran on IA64?)

FORTRAN is on the layered products DVD. Please note that it is the
F90/95 compiler only NOT the F77. I support some code that originated
in 1976 and has some portions that need to be modified to work on the
I64 platform. If you are upgrading from Alpha and use the /F77
switch, be aware that changes are likely.

The 2 main categories for me thus far are:

1) F90/95 no longer supports octal constants (the use of "007" for
example). This is nothing more than an annoyance as the code can
simply be changed to use decimal constants. These were left over from
PDP11 days.

2) The standard has always stated that there was no particular order
of evaluation for segments of an IF statement. In other words, should
you have an IF statement with multiple conditions that are logically
connected (.and., .or. etc) these segments can be evaluated in any
order. It seems that F77 often evaluated them in left to right
order. This is no longer the case and caused problems for the code I
support. Please note that the code should NEVER require or depend
upon this evaluation order.

I have VAX and IA64, but still not Alpha. If I want to complete
my collection of VMS systems, then I will need one, but not so far.

I was using OS/360 before any DEC systems, and so was more used
to hex constants. For VAX/VMS, I always use(d) hex.

I was not so long ago trying to get a program that I worked on
many years ago running again. With bounds-check turned on, it
would fail on such IF statements. In most cases, fetching element
zero of an array won't cause problems in actual code, but bounds
check catches it anyway.

There is some suggestion to add new logical operators to
Fortran, though still not in the 2008 standard. Maybe for
the next one.

Was there ever VMS Fortran on IA64?

Early on, there was talk of using the Intel
compilers, but I'm reasonably certain that
never happened. But I'm also not certain
that VMS Fortran got ported (more correctly,
translated) to IA64...

I thought I knew that there was. Also, I have a license
for it. They wouldn't do that if there wasn't a compiler,
would they?

Oh, well, that's very cool then. :-) And to Glen, yeah I'd
say having a PAK for it would be pretty good evidence.

Just demonstrating my ignorance (or lack of knowlege?) here.
I've had no opportunity to get onto IA64.

OTOH, it's still true that this is the F95 version, right,
and that there was not going to be any further development
of Fortran for VMS? No F2003, let alone F2008...

Does Fortran for IA64 exist?

Will a VMS compiler ever fully support a standard beyond F95?

Or for free if you are lucky. :-)

Someone posted that it does.

I doubt it, but I am not an authoritative source.

Yes F90/95 exists for IA64. I use it every day. I am not aware of
any further development for it beyond bug fixes though.
