Forgive me for asking.. I need to do a few things, one is to run a shell script and invoque program "prgA" and pass the result of program A back to the shell script. I guess I can do:

BACK = /sbin/prgA; echo $?

A) is that correct?
B) how does prgA report the output back, using a simple write statement?

Thanks

Paul

erm that's the EVIL way.
Try
BACK=`/sbin/prgA`

For this one at least, yes, I've done many of those using little FPC shorts to enhance shell scripts.

Thanks Paul
