Function
Informs the High Level Scheduler subject program that a particular job is of great urgency and should not be made to wait before being made fully started.
Format
When format 1 is used, job number is the number that the system uses to identify a particular job. The operator can determine this number by means of a WHATJOBS command.
When format 2 is used, both jobname and username parameters must be present but their order is optional.
The text parameter is optional in both formats. If present, the specified text will be passed across when the High Level Scheduler is notified of an EXPRESS command. It is ignored by the standard subject program but may be used by an installation which has its own modified version of the H.L.S.
