Try getarg and iargc (section 3F in the IRIS-4D FORTRAN 77 Reference Manual)

	character*N c
	integer i,j

	call getarg(i,c)
	j = iargc()

	getarg returns the i-th command line argument
	iargc returns the index of the last argument

Most F77 compilers have some kind of getarg/iargc function. Some, at least HP,
have implemented it as an intrinsic.
