Display limiting keywords will restrict the amount of output generated on the display command. This can be particularly useful for automation to parse the result of a $D command. For example:

$DOJOBQ,JM=RMF*,PRMODE,OUTGRP,ROUTECDE

This means to scan all queues for outputs that start with a jobname of RMF™ and display the PRMODE, OUTGRP, and ROUTECDE:

$HASP686 OUTPUT(RMF) 458
$HASP686 OUTPUT(RMF)       PRMODE=LINE,OUTGRP=2.1.1,
$HASP686                   ROUTECDE=LOCAL

Filtering keywords can also be added to the command for more granularity.

Selection limiting keywords can be viewed as filter keywords. Again, these keywords will appear on most $T and $D commands. In other words, the values you want to modify or display for a given job, on which it should take effect. In order to tell JES2 this is a filter keyword, the keyword must be preceded by a slash. For example:

$TOJOBQ,/FCB=JFB,FCB=ABC

This will change all output groups that has an FCB=JFB to ABC. Multiple filtering keywords can be used:

$TOJOBQ,/FORMS=123,/OUTG=1.1.1,FCB=456

This means to scan all queues for output of a FORMS=123 and OUTG=1.1.1 and change the FCB to 456. Additional modification keywords can be added to the same command as well:

$TOJOBQ,/FORMS=123,/FCB=789,QUEUE=A,ROUTECDE=PRT5
