None. My recollection is that SWA above the line came in with MVS/SP V2 (MVS/XA) R2 - MVS/SP V3 (MVS/ESA) at the latest. Long before OS/390 and z/OS.

At which release of z/OS did IBM move the JCT above the 16M line and initiate the use of SVA's? We have a couple of installations at earlier releases and we want to make sure that the SWAREQ macro won't fail there. 2. The macro IEFZB505 has two options for the keyword parameter LOCEPAX in unauthorized mode: "YES" and "VR2". When should either be used?
