Interesting enough to make me go search. For a change I jumped to RTFMing with PF1 and it shows:
Purpose: Limit the jobs that are displayed by job name. (In some cases, this involves columns other than JOBNAME. See the note at the end of this topic.) ... With the PREFIX command, two additional columns may be used. For jobs that entered the system through the TSO/E Interactive Data Transmission Facility (netmail), SDSF compares the value for the PREFIX command with a value that is displayed in the Wtr column (output external writer name) or as part of the Dest column (JES print destination name). Does this help?

For reasons almost lost in antiquity, the sequence avoided purging jobs/tasks that begin with S. When I first noticed several hundred jobs in the output queue (SDSF command O), I started looking for a pattern. I issued the PREFIX A* and saw a few but they were recent. I then issued PREFIX B* and dozens of jobs name SU00Y appeared. (If it matters, the prefix commands were entered in lower case. I capitalized them here for ease of reading.) I have never seen a response that didn't match the prefix before. This is on z/OS 1.11. Thoughts anyone? PS - After finally recalling the reason for this, the fix to the command sequence is to add $PJQ(S*),JM!=SYSLOG,A>7 but I'm still curious why SDSF thought SU00Y matched prefix B*. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ******************************************************** For information, services and offers, please visit our web site: http://www.klm.com.
