Most (actually all of the ones I've dealt with (SGI, SUN, HP, Cray UNICOS))
UNIX Fortran compilers have some form of a GETARG routine which returns
command line arguments. In the case of SGI there are 2 routines: iargc and
getarg. iargc is a function and returns the number og arguments:
      j = iargc()
getarg returns the i'th argument in the character string c:
     call getarg ( i,c)
Check the Fortran reference manual pages for more info.
