IBM 3270 Information Display System: Color and Programmed Symbols (1979) [pdf]
bitsavers.orgquite a collection of documents. I was looking for CICS related manuals but I could not find them.
Thank you for keeping this
if you mean you couldn't find them on bitsavers, look under ibm/370/CICS
Very nice, thank you.
Great! Still in use today at some retailers like Costco and Best Buy!
If it’s not broken, don’t fix it.
3270 is a very efficient form of distributed computing where terminals and their controllers control a lot of state and the mainframe is in charge of the more important things. It was a browser from the 60’s, mostly 70’s.
There are packages available that screen scrape 3270 streams and reformat them to export as html.
It’s really a quite simple transformation. All the core ideas are the same, just the presentation is different.
Close! Costco is 5250, which has many similarities.
They are a very famous AS/400 shop.
Heh, up until a few years ago our inventory system ran on an AS/400, and we had to use 5250 emulators to log in. Don't miss it.
The problem wasn't the AS/400 (IBM i) it was the 5250 interface. That's throwing the baby out with the bath water.
And even then, as with any other UI model, application design plays a massive role.
A lot of gas companies are too, especially on the distribution side. Actually AS/400, and VMS. And very recently.
VMS is very good for high-availability systems.
