That one is pretty good, except for the lack of USS and the fact that it only goes to 2GB.

The multiplicity of isolated user virtual address spaces which gave MVS its name and strong inter-user protection properties is shown by stacked "User Area"s and "Extended User Area"s, a diagram subtlety which would likely be overlooked by someone who didn't understand the significance. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
