The pipe name is a data set name. The scheduling problem is real: How to ensure two jobs run at the same time. I would propose common predecessors and common successors. Some of these might be dummy operations.
Actually, sorts are nice cases as they often read data that has been freshly created or create data that is just about to be read sequentially.

And perhaps more important, what if several programmers unknown to each other concurrently submit job using SUBSYS=PIPE; how do they avoid mistaken identity? Must a scheduler sort it out? I've had corresponding problems with sockets and dynamically assigned ports: someone needs to note the port number and communicate it to the other. >>-----Original Message----- >>From: IBM Martin Packer >>Sent: Wednesday, September 23, 2020 4:31 AM >> ... >>Something also from the mists of time, by no coincidence, is this: >> > https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.icea100/ice2ca_Example_11._Sort_with_Pipes_and_OUTFIL_SPLIT.htm -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
