Re: Paddle temporary fix?
Jim, Great information; thank you. I worked for EDS in 1978; they were still running OS/MVT 21.8 at that time, supporting five Blue Cross and Blue Shield plans in the Northeast.

They do not support whatever is in TCBPKF. I have seen code in TSO which has hardcoded x'80'.

With CPU power in such abundance everywhere else, it makes perfect sense to spend CPU time to save developer time.

Allocating datasets shouldn't be that hard to grasp. "Dataset" is actually a pretty common term and generally implies a collection of data with more structure than just a file. If people have worked with databases, presumably they have encountered the concept of defining the schema. A dataset is simply a collections of records (similar to a database table) where each record has a fixed length or limited variable length and the total collection has a size limit. Any structure within the records is up to the application. This is not an unusual construct. What is unusual is that z/OS uses such a structured format for almost everything, not that it exists. -- Andrew Rowley Black Hill Software -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: How long for an experiened z/OS sysprog to come up to speed on a new environment?
Eons ago, I tried out the RACF ISPF panels once. Took me 10x as long to navigate to the panel as just typing the actual line command. What those panels should do, but I don't know whether they do this or not, is display the line command as it's executed. To this day I don't understand why experienced systems programmers and experienced security officers use the RACF ISPF panels. That said, I will be writing ISPF panels to let coworkers use my personal productivity tools. /Leonard David Spiegel wrote on 2/21/2023 9:47 AM: Hi Doug, I consider relying on ISPF Panels *solely* negative, especially when SysProgs should learn the Command Line, in particular for RACF Commands. This is a sign of laziness. I've also been in jobs where I maintained/added to ISPF Applications to e.g. create a z/OS Clone, where the user fills in the "from" and "to" DASD addresses and the ISPF application does the rest. BTW, I am referring negatively to people who rely upon ISPF Panels *and* have never heard of CBT. There is no need to get offended.

My answer is that the people in charge are by-the-book mentality and I can imagine them using ISPF Panels for everything from RACF to SMP/e. (At one of my jobs, the MVS Team Lead said : "CBT??? ... never heard of it" (This guy has been an MVS Systems Programmer for more than 30 years.))
