Just for this instance, I'll reply. :-)

This is a good characteristic -- I'm *usually* not the MTT guy, but

I need a list of environment variables that you find in BProc jobs

- an environment variable (or variables) that can be analyzed to tell
me how many processes are supposed to be run in this BProc job
