Re: Help with fortran standards

[Arjen Markus <arjen.markus895@gmail.com>]

Hello Allessandro,

these are fairly general questions, whereas this list is meant for specific
questions on the gfortran compiler. You can post these on the Fortran
newsgroup comp.lang.fortran or on the Discourse group at
https://fortran-lang.discourse.group/.

However, here is my reply:

   - Compaq Visual Fortran has been out of support for several decades. You
   can use the Intel oneAPI suite as an alternative
   - CVF may have supported the Fortran 95 standard (I do not quite know
   the details), but procedure pointers are a thing of Fortran 2003. So it is
   very unlikely CVF will ever be able to compile your program

Regards,

Arjen
