Yea... I should have said "generally used".  And perhaps slightly less than
20 years.  In an offline conversation I just had with Art, I had to look back
at my resume to be sure.    My first exposure to MVS was MVS SP 1.3
in 1985 - an "express" system.  It had an ICF MCAT,  but I also recall 
a few VSAM catalogs on the system.   Otherwise I would have never
learned about the joys of vsam catalog volume ownership and defining
vsam space.
