Re: SVRB for LINK, when freed?
whether the SVRB for a LINK is freed before the LINK'ed to program's PRB is placed on the RB chain. After. But before the LINK'ed to program gets control. An SVRB is never freed before the SVC routine is done (and part of the doing of the LINK SVC routine is to queue the PRB). In fact (unless this has been rewritten without my consent) programs executing as a result of EXEC PGM= are (normally?) invoked via LINK, and they run under a PRB (or used to). If by programs executing as a result was meant the program identified by EXEC PGM=, not in fact. That program gets control via ATTACH. It does run under a PRB.

I believe the new PRB for the LINKed-to program is queued *between* the currently executing SVRB for the LINK SVC and the RB of the SVC 6 issuer.
