CICS on Visual COBOL

That's a tall order. CICS is not trivial.

My best suggestion is to start with the IBM CICS programmer documentation, namely SC34-7022 (the CICS Programmer's Guide) and SC34-7023 (the CICS Programmer's Reference). Those can be found in various forms on IBM's site; search for the publication numbers.

Besides that, there are any number of web pages dealing with CICS basics, though I'm not aware of a good, well-rounded tutorial.

Note that in order to use CICS with Visual COBOL you'll need either Enterprise Server or Enterprise Server for .NET.

Thank you  very much Michael, actually I asked for this here because of this "Besides that, there are any number of web pages dealing with CICS basics, though I'm not aware of a good, well-rounded tutorial."

I've also checked Murach's CICS book but the problem is that I can't get my hands on an execution environment, anyway I will start with the manuals you've mentioned and then see where it goes.

Best Regards
