No HLASM no z/OS. The sheer volume of assembler code is an existential threat to the platform as young guys don’t want to spend 10 years onboarding. > but mainly because over the last forty years, and long after even COBOL II > added functions and a case construction in 1987, very, very clever people > decided they would write application modules in assembler... and not waste > time with comments.

I heard an amusing story that IBM were hell bent on migrating to OO PL/X which was so buggy the CICS team in Hursley referred to it as “oh oh PL/X”. It was in the 90’s when everybody thought inheritance was a good idea but it introduced “is-a hell” and the path length of the code exploded. It was so bad that DB2 utilities were close to missing their targets and abandoned it. It was a huge blunder. A lot of new code in DB2 Utilities is done Metal/C/ > > Not to denigrate assembler programmers, or those that decide to take up > Sanskrit, but it is a dying art. Yep. For new code avoid it like the plague. But the legacy needs to be maintained. > > ---------------------------------------------------------------------- > 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 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
