I don't have a clue yet, but as said in my previous post, I suspect some storage overlay. Results are unpredictable. >(The x'0000' seems to be left-over garbage.) It is more likely it is fresh storage after the page was initially assigned to newly getmained storage. It will be cleared to X'00' by MVS. If nobody writes before reading it, it is still x'00', i.e. garbage. >BTW Why load offset x'90' on R7 as EP? I don't have clue. The storage where R7 point to belongs to a load module is called SQLBATCH and it seems to belong to Smart/Restart. Not our code. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
