See the getarg(3F) man page in the Iris-4D Fortran 77 Reference Manual 
Pages (Doc. number 007-0621-030).  It can be used as follows:

         character*1 iargc,jargc
   c
   c-----get arguments from command line
   c
         call getarg(1,iargc)
         call getarg(2,jargc)
         read (iargc,'(i1)') iarg
         read (jargc,'(i1)') jarg

The calls to getarg return the 1st and 2nd arguments in the character
variables iargc and jargc.  The internal reads convert the character
variables to integers.  Note that this example is for single digit
integer arguments.

That's OK.  I'm just an engineer.
