Our warehouse has a dedicated printer for B/L's (Bill's of Lading) and when they needed have one printed, they had to select the process off a menu, key in an order number and then exit the program, only to have to go back into the program seconds later. They wanted to keep the program open, but programmatically, this would not 'release' the spool file. To get around this, I literally defined the spool file in the RPG program as a user-defined open file and within the looping code. I would open and close the file, which would free up the spool file for printing.
