I'm having troubles bringing my FORTRAN application to the Mac.
I've tried 2 compilers (they will remain nameless) that don't make it.

I need a compiler that can do the following (in order of importance):

     1) Conforms to the F77 standard (including the character
         handling operator // and the character functions
         LEN and INDEX).
     2) Handle tons of COMMON blocks and BIG block data subprograms
         (maybe 3-400 real variables in COMMON). I take no blame
         for this! :-)
     3) Allow "calls" to the operating system (ie get a list of
         all data files, print files, erase files)
     4) Have some way of getting the system time and date into a
         variable. 

Unfortunately, conversion to C or any other language is out of the
question. 

Thanks in advance.
