Variables only hang around as long as filePro is running.  Once filePro 
exits, all variables are gone.

Is this variable being set by the first processing that runs?  If that's the 
case, I would suggest using PUTENV to set an environment variable, SYSTEM to 
the other programs, and GETENV to read that variable.

(Just like filePro variables, environment variables "go away" once the 
program exits, so you can't set it in the first dreport, exit, and expect it 
to still be set.)
