The comments in the copybook, SPOOLHK.CPY explain the field values
05 ws-run-frequency pic 99999 value 1
Change the value of ws-run-frequency to the number of days that you want to elapse between runs of spool housekeeping.
Note: The ws-run-frequency value is used only if the spool housekeeping is run using CICS. It has no meaning with the recommended method, that is when you schedule a batch job to run spool housekeeping.
05 ws-keep-for pic 99999 value 6
This is the default retain period and applies to ALL spool output. Change the value of ws-keep-for to the maximum number of days that you wish to keep spool output for. (This includes: i) Any held output for SYSOUT classes with no specific retention period ii) Any output that was scheduled for printing which is still on the spool print queue)
Note:
The retain interval is in days. Using one day is not recommended as a run shortly after midnight would delete spool files written the late previous night; that is, files that are only a few minutes or hours old.
