I hope that you weren't expecting me to take that bet. 99% of the users also didn't know what BAL, drums, GJP or SGJP were either. The world is divided into two kinds of people; those that never experienced a noodle picker or Mother Fletcher, and those that wish they hadn't. > How about here That a legitimate diagram. The one that the OP metioned was deliberately obfuscated to make it look more complicated than it actually was. It was a true classic. -- Shmuel (Seymour J.)

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.
