Re: JCL DD SUBSYS - how to write the SUBSYS
Hi If you still interested, I wrote couple of years ago a SUBSYSTEM use APPC (LU6.2) to access PC data something like this: //OUTPUT DD DSN='T:/miklos/K0917.MVS',DISP=SHR, // DCB=(RECFM=VB,LRECL=8192), // SUBSYS=(QNTA,'SYSTEM=OS2APPC9,DATA=AFPDS') I can give you the source offlist.

The Subsystem Interface in MVS/SP Version 3 GC66-3131-00 August 1989 I have a hardcopy of a pre-publication draft of this book. It was from WSC, but I don't know what color the published version was. The authors of the book wrote an assembler language subsystem which was originally going to be included with the book as a sample program. That code ended up being rewritten in PL/AS, renamed as Batch LSR, and shipped as a PTF on top of MVS SP 3.1.3. The original assembler code is probably long gone. I thought I had kept a copy, but: ARC1010I USER REQUEST FOR A MIGRATED DATA SET FAILED.

Re: JCL DD SUBSYS - how to write the SUBSYS
Having fairly recently developed such a subsystem I can confirm that the General Purpose Subsystem Access Method (I believe that's what the acronym stands for, our systems in Dallas are down today so I can't check directly) is a decent introduction, although it glosses over a lot of issues which need to be resolved for a practical stable application, if you're doing something non-trivial. Also the iefssi, iefssvt, iefssvti descriptions in Using The Subsystem Interface and Auth Assembler Reference are required reading. As far as accessing DD parameters is concerned we needed to scan the text in the C/I exit and look up the RB chain in Group Allocation to find the Dynalloc SVC parameters in order to get all we needed. So there's some quite interesting work involved. -Ursprüngliche Nachricht- Von: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] Im Auftrag von Anthony Fletcher Gesendet: Sonntag, 15.

Re: JCL DD SUBSYS - how to write the SUBSYS
Well, Batch LSR Subsystem(BLSR) started out as a sample of how to write a subsystem, IIRC. I think it was in a WSC orange book. But I don't know how to locate it now. Anyone?
