It's a scripting language that originally built JCL but apparently has been enhanced to actually "do" JCL functions like dynamically allocating datasets and running jobs.

Never heard of it. I'm repeatedly surprised at the number of mainframers who never learned JCL past the ability to modify a job by replacing a DSN or two. Yet somehow they manage to function, sometimes by asking someone else to help fix their JCL. A new employer put me through a Deltak course in JCL when I started with them in 1980, and I've been using it ever since, usually on a daily or weekly basis. I'd hate to have to work without it. --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* It is not always the same thing to be a good man and a good citizen. -Aristotle, "Nicomachean Ethics" (325 BC) */ -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Pommier, Rex Sent: Monday, March 27, 2023 16:29 Sorry, I'm going to "rag" on a language... :-) Admittedly I know next to nothing about it. My exposure to it consists of reading an article where somebody took a 14 line JCL job and converted it to JOL and the JOL code ended up somewhere around 70+ lines plus comments to explain what the program was doing. It appears that JOL now does a lot more than it used to do the last time I actually looked at it. However, in JCL's defense, how many people actually build jobs (especially more complex multi-step jobs with IF/THEN, conditional execution, etc. from scratch? Same as with a typical Cobol program, you take an existing program or JCL member and modify it to fit your needs. How many people here use JCL (whether you like it or hate it) on a regular basis? It's ubiquitous. How many use JOL? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- The information contained in this message is confidential, protected from disclosure and may be legally privileged.
