What is CICS and how to use it.
Learn COBOL Programming.
COBOL Tutorial.
A CICS application is a collection of related programs that together perform a business operation, such as processing a travel request or preparing a company payroll. CICS applications execute under CICS control, using CICS services and interfaces to access programs and files.
CICS® stands for "Customer Information Control System." It is a general-purpose transaction processing subsystem for the z/OS® operating system. CICS provides services for running an application online, by request, at the same time as many other users are submitting requests to run the same applications, using the same files and programs.

thank god finally one of these without an indian accent

[@poloola7569]

same thought but they are really good at tech.

@@poloola7569really good at tech but really bad at communication, not only the accent.

I worked on a CICS system (utility customer service) back in the 70s and 80s, when most of the transactions were written in Assembler; the majority of which were limited to 12K bytes. The mainframe probably had 8MB of storage - and was supporting up to 2000 terminal operators - with under half second response..
Migrating to Cobol and Command Level was quite a revolution.

I 'retired from CICS' 16 years ago after working with it for 26 years. Fascinating to see the zOS elements which were barely beginning to appear when I signed off!
One minor observation: the start rather implies that CICS is for the finance industry only. Its true power is its flexibility across all business areas (manufacturing, commerce, government), and across a huge variety of enterprises from tiny (CICS on a 370/125 with 128K) to enormous.

I was a system programmer back in the 70s. I remember updating the CICS tables for new programs, terminals & databases. You had to shit down CICS and re load it to bring in the new tables. CICS 1.3 under DOS/VSE.
The first 4 characters of the 3270 stream were blanked out so an application could plug in the 4 character program name of the next program to run when any PFAID key or ENTER key was pressed.

Thanks for the vid. Nice refresh. I was a CICS programmer in the 80's and 90's. Fun Times.

In 1989 I choose COBOL under DOS 3.3 (over DBase III +, which rest of the classmates choose as they feared COBOL compiler errors :-) ) wish I could get my hands on a mainframe till this day.....

[@locusf2]

you can run a mainframe with hercules emulator, using MVS 3.8 TK5 by Rob Prins

[@BarfingGerbil]

There's Hercules and TK5 (and it's direct older version TK4-), and there's WATBOL on MUSIC/SP (Under Sim390 for Windows or Hercules). Also, for TK4- and TK5 there is a CICS emulation available called KICKS.

[@sergegirard9712]

Wish I had that years ago! Thanks!

[@overlordl1]

good

[@alihamchou9278]

Hi thank you so much , my job was system administrator on mainframe
I left this job since 2006
How I can refresh my info
VAS/ESA
VSE 2.1
Ciccf
Vsam and Sam file
The difficult job was unload and reload data
Because in that time Need to do this procedure every month
To delete the gaps inside hard disk
Now big gap between 2006 now 2024
but it was an amazing job never have it again

[@scottstempmail9045]

Now do TPF.

[@bzert281]

(spits coffee)

[@chartchart]

And then you got a VSAM DATABASE harhar
