It's not free, but z/XDC will do the trick. Even more, it can also zap storage that's been made "read only" (such as the PLPA, "read-only" sections of the nucleus, and any other page that has been made read-only by the PGSER macro). If your client has z/XDC, then this would be an easy way to accomplish what you want. Dave Cole ------SNIP-------------- A LONG time ago we had a company (hazy to the name but it might be SEI) that had a memory zapper it was supposed to be used only in CICS regions but it grew to wide use by quite a few people. It was probably the single most reason why our system(s) crashed so often. We had a few "experts" that while dangerous were almost criminal (story ends there). A few years later when the company was just about to go out the door (thank god) some blankity blank programmer convinced management to keep it around. Though our system crashes were reduced they still occurred. We had a IBM PSR at the time and if found anything remotely pointing at the product he would refuse to work on the problem anymore (couldn't blame him really). Fast forward 2 years and one of the divisions hire a reasonably good assembler programmer. He got so good he was using the cross memory zapper everyday and low and behold the crashes increased but not as bad as before. I was really happy to get out of the place as the stand alone dumps were stacked higher than the top of my cobicle (not a true cubicle but close enough for my purpose.
