I was thinking that, so it means if I do something like: LARL R2,SOME_LABEL
while in AR mode, I need to follow that up with another instruction to set the AR2 to primary mode unless I am certain that AR2 has not been "messed with". E.g. do: LARL R2,SOME_LABEL LAE R2,0(R2,0) SET AR2 TO ZERO I guess that I really want LARLE to set AR2 as well a GPR2. Many thanks. -- While a transcendent vocabulary is laudable, one must be eternally careful so that the calculated objective of communication does not become ensconced in obscurity.
