I never saw the initial post, but the program provided as an example with the BR 14 was incorrect. It was off by a level of indirection.
This was what was posted: MODESET KEY=ZERO,MODE=SUP STORAGE OBTAIN,LENGTH=2,SP=227 LR R5,R1 MVC 0(2,R5),=X'07FE' IEAMSCHD EPADDR=(R5),ENV=STOKEN,TARGETSTOKEN=STOKEN Ignoring the fact that this is somewhat wrong if reentrant (as it ought to use list/execute forms), when a reg form is used for IEAMSCHD, the reg is to contain the address of a word that contains the entry point address. Your reg contains the address of the routine itself. As coded, this SRB uses as an AMODE 31 entry point x'07FExxxx' and (if you're lucky) blows up and will have no effect whatsoever on the issuing task or the target space. I suppose if you're unlucky there could be instructions at that address and just about anything could happen. If you want the SRB to run synchronously with respect to the caller, you could consider the SYNCH=YES keyword of IEAMSCHD. I do find it distressing that experienced people on this forum would give advice about using non-programming interfaces such as CVTSRBRT. I urge the originator of this thread to try to find someone local who has addtional experience to provide some guidance with respect to writing authorized code, to avoid adversely affecting a customer's system, either functionally or integrity-wise. It was mentioned that the desire is to do VSMLIST. Why? What will you do with the information? Maybe there are other pieces of information available in the system without going through the trouble (and cycles) of retrieving VSMLIST and analyzing the conl structures.
