If you are using Unix or Mac OS X, you can use the various redirection
capabilities of those operating systems. For example, put the inputs
in a text file, and then,
SPAWN, 'my_fortran_program < inputfile.txt', output_results

If you need dynamic control, you will want to use the UNIT keyword for
SPAWN, which provides a file unit you can write to. I.e. you would
PRINTF your inputs to that file unit. That can be very subtle
however, so it's better to use the above construction if you can.

If you have windows, I'm less well informed.

Good luck,
Craig
