Folks:
      i am interested in any commercial/institutional software tool
that checks the non-portable features of existing and new
FORTRAN source for use in the UNIX environment. The software tool
should ideally have been ported (!) onto several  platforms and should
check for deviation from ANSI Fortran 77 (8x or 90 a plus) and warn against 
potential compiler traps.
     
       i would appreciate any info/leads on the above. i
seem to remember the NAG (?) group having written some tools
that would do this ? could anyone give me information or
persons i can e-mail to ?

        Thanks in advance.

PS:
    i will post replies if people out there are interested.
