It's about six lines of code that assumes you have less than a few petabytes of real storage, and that I'll leave as an exercise. Don't try this at home. It's rather dangerous code if you load the registers pointing to memory that actually does exist. I've seen many (far too many) dumps in my time, and that is definitely a unique PSW. sas
