JOBPREFIX=<up to 3 prefix characters>

Example:  JOBPREFIX=JOB

Default:  JOBPREFIX=TSK

JOBPREFIX allows you to override the default jobname prefix ("TSK") which is used to generate unique job names. The prefix is normally 3 characters, to which A-Shell appends a sequentially generated suffix (e.g. "AAA", "AAB", etc.) resulting in job names like TSKAAA, TSKAAB, TSKAAC, etc.

Job names can also be specified by the TRMDEF statement or by use of the –j <jobname> command line argument.
