Hi, I'd like to catch the output of an SMS command, like 'DISPLAY SMS, STORGRP(ALL), from REXX. Is that possible? I've tried some ideas with no luck. Thanks, Horacio ________________________________ De: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> en nombre de Pommier, Rex <rpomm...@sfgmembers.com> Enviado: lunes, 16 de mayo de 2022 16:51 Para: IBM-MAIN@LISTSERV.UA.EDU <IBM-MAIN@LISTSERV.UA.EDU> Asunto: Re: [EXTERNAL] Re: IBM BLSR subsystem
Thanks, all responders. Michael, so I'm not stuck in the mid '90s, just the BLSR documentation is. :-) "First Edition, June 1994" I have seen the references to BLSR in other documents, like a crypto manual and some SMP/E references to it, but until I found the 1994 document, I couldn't find anything that actually explained it. That's where I was getting confused. I'll also need to check the AMP parm to see if that does the same thing. The DEFERW=YES option looks interesting (again).

Otherwise, just increasing the BUFNI and/or BUFND will suffice. Note that for sequential access a BUFND of twice the CIs per CA plus two and just a few BUFNI five or so) usually provides about the best you can get (incudes over-lapping read I/O to the data component). I still see BLSR in the 2.5 IEFSSN00 member.
