The QT (Quit) command terminates the printing of a backup file. QT is equivalent to PS REQUEUE <device type> when the file is being processed by the Print System; however, you cannot use QT for files being printed by the Remote Printing System. The backup file remains in the directory and can be printed later with a Work Flow Language (WFL) PRINT statement, the SYSTEM/BACKUP utility, or a command such as PS  MODIFY <request> if the file was processed by the Print System.

You can also use the QT command as a response to certain RSVP messages issued by the system, such as the following:

PK <unit number> RESERVE INCOMPLETE: OK TO PROCEED, QT FOR RESDISK

Syntax

Explanation

When you use the <mix number list> QT command for backup disk files being processed by the Print System, the file currently being printed stops printing and is marked as an exception. However, the system does not remove the file from the disk directory. The equivalent Print System command is PS REQUEUE <device type>,where <device type> is a site printer (not a remote printing device) being serviced by one of the programs in the mix number list.

If the mix number you specify is for a TAPEPRINT task processing a backup tape, the system terminates output for the current file. TAPEPRINT then spaces forward to the end-of-file marker and begins printing the next file on the tape if one exists; otherwise, the tape rewinds

If the mix number you specify is for a SYSTEM/BACKUP process, SYSTEM/BACKUP skips over the file that is currently printing and continues printing with the next file in the list. If the terminated file is on tape, SYSTEM/BACKUP spaces the tape forward. If the terminated file is a backup disk file, SYSTEM/BACKUP does not remove the file from the disk directory.

The QT command has no effect on a process that has been locked by the LP (Lock Program) command.

Examples

Example 1

This example terminates the printing of a backup file:

6823 QT

Example 2

This example shows the command sequence to use if a task is locked:

2420 QT

   PROGRAM IS LOCKED

2420 LP -

   2420 NOT LOCKED

2420 QT

(The system does not respond this time.)
