<snip>...the logic above is done on _every_ OPEN for _every_ DD name. Or is it only if the OPEN is for a DCB which is BPAM (i.e. the DD concatenation is for libraries)? </snip>
I'm not sure, but since APF authorization applies only to load libraries, I'd imagine that the OPEN processing is done only for cases where it applies. <snip> IPLINFO is a REXX exec. </snip> I believe you. The code that was shown was assembler. Regardless, being an exec still means that the choice was made not to use an intended programming interface.
