Peter: Long time ago and when MVS first came out, we used to do this quite often (once a week). A product we had called DUO (DOS under MVS). DUO maintained a table in the nucleus for which dos jobs were running. They had a bug in their code that would not delete entries. We had to go in and blank out the job names that were not running(so as not to have to IPL). We finally got tired of doing this and wrote a program that did it. Worked like a charm. They asked for the program and we were not in a good mood so we said no. It took them a year to figure out how to do it.My memory is hazy here but I think the degression was “duo” -> went to some company in Dallas? and then a year or two later CA bought them out. By then we had gotten rid of all the jobs. One of the long time contributors to IBM-Main used to work for the company if he hasn’t retired maybe he could speak up?
