The Ultrix f77 still appears to be the same fortran to intermediate C code generator that bsd4.2 f77 is based upon. I would believe that DEC has tuned the code generation to improve execution (as well as fix some bugs). It would be nice if VMS Fortran were ported, it is much nicer to use (as in much more user friendly). -- Gary W. Kenward Mobile Data International Inc. Riverside Industrial Park Richmond, B.C.
