  VMS Fortran has been available for Ultrix (at extra cost) for apx. 18 months.
  I had it used for the conversion of a large program (from a DEC-20). Overall:

  The resulting executable crunches much faster than f77;
  It requires a prorietary DEC 'language' to interface VMS Fortran modules to 
  other languages;
  The result appears to be totally non-portable;
  We encountered some highly "unique" bugs.

VMS documentation is often "understandable", but UNIX documentation is
ordinarily much more complete and accurate.

Also, HP Fortran on HP-UX 2.0 has many of the popular VMS Fortran features.
