Sorry, but I don't think the evidence exists to support your assertion. TSO Pipes were never generally available, so people didn't get to use them much. That means we don't know whether they would have, but the huge uptake on CMS -- where the kinds of things that one tends to do with a Pipe are generally easier to do than in TSO anyway -- suggests (does NOT prove) otherwise.
You saying "TSO PIPEs aren't useful" suggests to me that you haven't really seen the power of Pipes. Many of us have written products that comprised mostly Pipes, or condensed hundreds of lines of Rexx code down to a dozen-stage pipeline that ran orders of magnitude faster. Yes, COBOL might (sometimes!) be faster to run -- but is (generally) slower to develop, debug, maintain. People's time is expensive... -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Jon Perryman Sent: Monday, September 8, 2025 5:05 PM To: [email protected] Subject: Re: Pipelines = you don't understand z/OS On Sun, 7 Sep 2025 18:24:29 -0500, Hobart Spitz <[email protected]> wrote: >Why haven't customers jumped on Pipes (CMS/TSO Pipelines), like they >should? Here are some possible answers: Native TSO PIPEs existed but customers refused to buy it. z/OS Unix pipes has nothing to do with TSO PIPEs. If today, you absolutely needed pipes in TSO, then use z/OS Unix pipes despite it's downside. I repeat, TSO PIPEs aren't useful otherwise it would still exist. It appears no one noticed it's demise. There are better ways to solve problems that people perceive CMS PIPEs is supposed to address. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
