John, I'm not an AS/400 expert but I know a man who is........... Mark Phillips, one of our AS/400 developers wrote : - "It is possible that the program is picking up an old version of the service program. When programs / service programs are recreated on iSeries, the compiler moves the old version of the object to a special system library called QRPLOBJ. This has the benefit that any programs with cached pointers to the recompiled program/service program will not fail. The downside is that the new version is not picked up automatically. There are two possible solutions to this... One is to sign off and back on again (obviously not ideal, but if this doesn't work then you don't have the QRPLOBJ problem). The other is to reclaim the resources that your job is using, forcing a refresh of the pointers etc. You can do this with the commands RCLRSC LVL(*CALLER) and RCLACTGRP ACTGRP(*ELIGIBLE) One final point is that you should make sure that the QRPLOBJ library gets cleared down from time to time" Hope this helps, P.
