However, the contents of this virtual PSA do not correlate at all to the contents of the actual PSA, using XDC to interrogate and display. However, in looking at an SVC dump from a day or so ago for this same system, it appears the fields are valid. I then looked at an SVC dump from a customer, where there were 6 engines active, and each virtual PSA looked valid. So, SVC dump must know how to do this. If anyone knows how to accomplish this programmatically, I would appreciate them sharing this with me. Thanks. If you are looking at the PSA for the active CPU, you will be seeing the absolute PSA. As part of the hardware prefixing logic, if real page zero is referenced the prefix register is used to address the absolute page. If the real page matches the prefix register, absolute page zero is used. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
