Indeed, and do you then always use the LINKINST=BASR keyword on the CALL macro to force the macro not to use BALR? What do you do about the WTO macro which always generates a BAL around the message text? Etc., etc., pick your system macro and observe the BAL/R's and other ancient instructions all over the place. <smallrant> I am occasionally somewhat peeved at IBM for failing to provide different, non-24-bit macro expansions when the programmer goes to the trouble of coding SYSSTATE ARCHLVL=2 (or any other mechanism they might care to invent). Even GET/PUT could use BASR, AFAIK, unless they too are using the BALR to detect AMODE. Which ought to be documented, if true. </smallrant> Peter This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
