I suggest DSPOBJD thequery *QMQRY then use 5 or 8, there is a page that shows number of days usage and last day uses. I have not checked if info is correect for *QMQRY, but i am sure it is correct for *PGM.
After having targetted info for one query, uses DSPOBJD … OUTPUT(*FILE) for mass run
If necessary, you can turn number of days used to zero by
– rebuilding the object or
– changing this info with CHGOBJATR (available at http://jplamontre.free.fr/jpltools.htm)
