Qedit as an Operations Tool
Qedit is handy for managing :Stream files and spool files and coping with operational problems in general. For example, you can leave Qedit running on the console with SPOOK and Suprtool as “suspended” son processes for dealing with spool files and data files. While editing and launching job streams, the operator can use List filename to examine other files and dump them to the printer.
