Re: Format PDS unloaded on an CD

Re: Diagram of MVS Control Blocks
I'll bet 99% of people -- even those who ran OS/360 -- didn't t know what Roll out / Roll in did. I found it included in Mitre OS/360 SYSGEN when I joined company in 1971, laughed, exercised it, removed it -- saving xxKB from resident nucleus, back when bytes were precious. It enabled JCL options, something like Rollout=yes and Rollin=yes. Specify former, job was eligible to be pushed entirely out of memory to disk. Specify latter, job was eligible to push jobs out to make room. Or maybe that's backwards, or maybe those aren't the precise options. Some jobs designated as bullies, others wimps. Of course nobody at Mitre had ever used them; for grins I coded two jobs, one each. Ran wimp job, then bully job. Operator got a couple mysterious messages he'd never seen before about wimp job being rolled out and rolled in. Then I redid SYSGEN minus that pointless option. It was early primitive swapping.

Re: Printing GTF trace?
Widening the perspective. Versatile IPCS is used to analyze all sorts of dumps--SVC, standalone, SYSM--as well as GTF trace, which can be for hardware or software or both. So why is it so little used outside of the 'system programming' inner sanctum? At my one and only GUIDE conference in 1980, one session on IPCS focused on the question of usage. This was in 1980. At that time IPCS required SAF READ access to SYS1.PARMLIB. It had to be THE system PARMLIB. A copy would not do. The problem for many shops was that access to PARMLIB was prohibited by for general users. Meanwhile ISVs rallied to provide user-oriented products that cost money--IPCS is 'free'--but did not require challenging corporate security policies. Somewhere along the line IPCS's PARMLIB requirement was dropped, but it was too late to overcome the ISV offerings in the public mind. I was once called in to help with a COBOL application that was receiving inexplicable abends. The ISV product did not help. I set up a SLIP trap to capture the 'first abend', which turned out to be a run of the mill S0C7 caused by bad input data. That abend was further mucked up by an ancient SPIE routine that corrupted registers and created a different, wholly unrelated abend. So why is it called 'IPCS' anyway? Interactive Problem Control System. Originally IPCS provided an elaborate mechanism for managing an inventory of dumps and traces. That function disappeared altogether even as analytical functions were enhanced. Like, why is it called 'TSO'? There's no time sharing, and it's not optional. Old names persist like those carved on headstones. . .

I took that same two-week class in Chicago in 1980. The diagram in question (as I remember it) was a joke, right?

I too had a copy once, but it's long gone.
