Well you're right, but I wasn't even thinking of that aspect. I was just thinking of "why 64-bit?"
I would think you ought to be able to safely guess you could do a 30MB GETMAIN in 31-bit private. If every assembler statement generates 1000 bytes of ADATA, or rather, ADATA that you need to save and process (which seems like a high guess) then your 30MB GETMAIN could accommodate a 30,000-line assembly, which seems like a pretty good-sized assembly to me, especially if comments aren't counted. (If you don't like my exact numbers you are free to plug in your own and do your own arithmetic. I think you will reach pretty much the same conclusion.) In any event, such as if you disagree with my arithmetic conclusion, then I agree with David that 64-bit private would be a lot more convenient than a data space.
