Hello list,
Someone can tell me the relevant differences between the MVS and z / OS systems?
MVS was the prior name of what has become z/OS. What was started out as
MVS in 1974 was renamed to:
MVS/SP Version 1
MVS/XA Version 2 in 1981
MVS/ESA Version 3 (1988), Version 4 (1991), and Version 5 (1994)
OS/390 (1996)
z/OS (2000)
Along the way have come a plethora of new and enhanced functions. There
are more differences than there is time to list them. However, we still
call the "base control program" (BCP) "MVS" in many contexts, such as in
the names of various z/OS books, to differentiate it from the other
70-ish parts ("elements") of z/OS.
