Forgetting can be surprisingly difficult, however ardently desired. I still remember some opcodes from the 650, a machine that only a mother could love. Or the addressing structure of the 1005, a machine straight out of Adams and Wilson.

Do not click links or open attachments unless you recognize the sender and know the content is safe. I don't remember either, but I do remember that Relay had "Beyond .bat", a .bat-like language that did a lot more, used for Relay/Gold emulator scripting. That suggests that it was pretty weak. Doesn't mean anything you said isn't right, of course. (And I'm NOT sorry that I don't remember those details--best forgotten!) -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Seymour J Metz Sent: Monday, November 11, 2024 2:11 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: What is a "programming language"? Was:: Modifying JCL on the fly My recollection is that BAT had conditional logic since the original PC-DOS; I don't recall what it was like in CP/M. CLIST, OTOH, became a programming language in OS/VS3 3.8, as I recall. I may check bitsavers on that last. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
