@drj @oddhack Yeah, everything had to be in PDSs.
Then there was the time that notional "rent" for disk space was introduced. Which was calculated at midnight every night. So it didn't take long for the students to get into the habit of emailing themselves their files every night, then deleting them, then restoring them from emails in the morning, thus being charged no rent. From which it didn't take long for the Computing Service to calculate the rent continuously rather than just at midnight.
@TimWardCam haha. there were other odd places to store stuff. my INIT script (which had a length limit similar to the original Tweets, one record i suppose) stored most of the actual code in a JOB output, which it would COLLECT, run through ZED, and then execute (which resubmitted the job).
This was cool (haha) because while file access could be granted to other people, only me myself my actual userid could submit and collect jobs.
@TimWardCam @oddhack @drj oh man, those wasteful tracks! I'm an MVS survivor myself, and the idea of having to divvy up tracks myself was one of the most important factors to make me pick UNIX for my next assignment.
I probably would've been better off now if I had taken the proffered path of becoming an MVS system programmer, but the waste put me off it. Not to mention having been retired with a meaningful pension by now :-)
Ah, spreadsheet memories. And Lotus 123. Quattro Pro. Framework, anybody remember Framework Suite?
I was a Quattro teen, but occasionally used Lotus and later As Easy As for my DOS spreadsheet needs π
But consider this: 28kb was more than half of the physical memory on the device!
