George:
I would use system() or system_exec() (whichever 1 returns error codes)
& pass my input as either stdin or as cmd-line parameters.  The
returned values would be either via:
1. error codes,
2. stdout, or
3. thru a temp file interface.

I think I saw something in the archive that allows a EU prog. to use
COM or DDE.  That could be another option for passing data back &
forth.
