Re: How can I learn OS 390 /ZOS/COBOL FOR MVS,CICS ,ROSCOE AT HOME?



I would like to learn
How can I learn OS 390 /ZOS/COBOL FOR MVS,CICS ,ROSCOE AT HOME?
It would be better if I could do it by myself,with books.
Is there any kind of free emulator or a chep one?
So I could learn all these subjects in my Pc?
If it is not possible,There is any e-learning course that gives me
acess to Mainframes?

If you don't know ANY COBOL at all, you can learn "any" COBOL at all, even a
PC-COBOL. The differences between "any" COBOL and "Z/OS COBOL" are tiny.

CICS is different... that's a whole subsystem unique to the IBM mainframe
environment. But if the COBOL you learn uses a "CD" (communications
description) and "SEND" and RECEIVE" verbs, you can kind of get a feel for
how you have to program in that environment.

If you already know COBOL, then you can focus on finding CICS and ROSCOE
stuff because, as I pointed out, COBOL is COBOL. (After all, that is the
whole idea behind a high-level language).

While you are at it, you might also want to familiarize yourself with the
source code editors commonly used in the mainframe environment. I haven't
been on mainframe in a while so I might be out of date, but the TSO editor
and the ISPF editors are the ones I worked with, except once I worked on a
CMS system which used a different editor.
