Thanks.

i was able to get the script working.  g_spawn_async works great.  I am
now having a problem using the g_spawn_async_with_pipes.  The program I
am calling works fine as a standalone, but when I spawn it I have
trouble with it getting my input.  Any hints or progamming examples?

The vendor who wrote the program used scanf(%d,&cmd); to get the input
from the command line, BUT write() sends chars out one byte at a time.
Is there a way to keep the scanf in the vendors program?

Thanks,
Ed
