AFAIK smp (e) did not exist during mvs 2.0 3.0(shakes on this one) and it came out with 3.7 (?) Before smp there was tremendous and I do mean tremendous working by having to manually to the co, prerec's by hand. It was drudge work that needed a high amount of concentration and immersion. I did it once and couldn’t handle the long hours needed. We printed a spreadsheet and it helped a little but still took copious amounts of time. SMP was a godsend to sysprogs. I would venture to say that MVS would have ended up in the dust pile for computer history without SMP. Yes it was cumbersome and the PDS’s needed and large number of directories was a real pain. VSAM saved SMP as well.
