9.5. Job Scheduling - topq, holdall, noholdall, hold, release

The topq command effectively puts the select job or jobs at the top of the queue for printing.

The holdall, noholdall, and release commands implement a simple holding queue for jobs. By default, holdall is disabled. When the holdall command enables it, then jobs will remain in the spool queue until explicitly released with the release command.

The hold command can also be used to hold individual jobs until released.
