A *FEW* VMS specific features?  It's practically a different language!
At least it can be, if you use the extensions.   It is certainly possible
to write ANSI standard code on a VMS machine, but DEC certainly doesn't
encourage it.   Porting software written in Vmstran can range from easy
to nearly impossible; usually it's a pain in the neck...   I think Sun
has a tool that handles many of the vms extensions.  A lot of vendors
have extended compilers that can deal with varying amounts of them,
although I've never seen any converter or compiler that could correctly
handle all VMS extensions to fortran.

foreach f ( *.for )
   /bin/rm -f $f
   vi `echo $f | sed -e 's/\.for/.f/'`
end

 (but don't try this guaranteed conversion method unless you
  *really* know what you're doing...)
