initially set in the queue).
Lowest priority at which a job can be
entered and aged.
Highest priority a job can reach in the

reached. (Job is also given this priority
when initially assigned to central memory.)
in Interval at which jobs are aged while in the
queue.
Service limits:

individual job of the origin type.
Maximum number of jobs.

individual job of the origin type.
Maximum field length/100 octal for all jobs of
the origin type.

t
The entry in this field is not the actual value but an index to a table of values. Refer to the SERVICE command in
section 3 and find the parameter which corresponds to the S-display field (such as, the FCx parameter for the FC field).
The table in the parameter description shows the actual value. If the default value is used, the entry does not appear in
the display. .
