This section includes a very brief history of z/VSE. To the many seasoned z/VSE veterans with lots of experiences and memories, we apologize for leaving out so much. To the z/VSE newcomers, some of whom may not yet be 40 years old, we apologize for including so much.
Disclaimer: The facts contained here have been checked and rechecked. However, 40 years is a very long time and memories fade. There is no guarantee the author's memory is correct in every aspect of the last 40 years. Indeed, the reader may remember things differently. That does not necessarily imply that either view of the past is wrong.
