Can anyone help me where I can get a dcument which has the basics for REXX/CLIST.
I went through lot of books trying to learn them, but those books seems to be covering a hi-fi knowledge about them. So I need some basics of REXX/CLIST as I am unaware of even A,B,C,D of REXX/CLIST.

Thanks in advance,
Harry.

if you are unable to find information on the web,
i doubt that you will be able to master the concepts required to write/test/debug any scripts.

Harry I found the IBM REXX/CLIST books more easier to learn as they are like self learning books

You can refer the link for

REXX &CLIST here

More importantly you need to work with them rather reading them

It might sound difficult, but you can cross out half your workload: you do not need to learn about CLISTs. CLIST is an archaic language that should not be used for new development.

Pedro,
you are assuming that he knows that they are two different languages.

It's 2012, suggest you invest your time with REXX rather.

The browser at my end is malfunctioing, I wanted to change my post; and until I submit, I did not see the reply from Pedro, but I'm caught... icon_cry.gif.

Alas, weekend is still away and weed waits for now, John...icon_wink.gif

On ther other hand, just for the sake of differntiation, CLIST is explicitly linked to TSO/E, whereas it is possible to run a REXX exec outside of the TSO/E environment. REXX can be compiled, CLIST is always interpretive.

There are some freeware also for REXX, such Regina REXX is my favourite these days - it's Fun. OOREXX is also good, but I prefer Regina.

when you are in the preview panel (entered after clicking on PREVIEW)

at the bottom of the webpage, the previous posts are displayed,
by clicking on PREVIEW you can refresh the page,
thus seeing those posts that are 40 minutes or so old (actually, any posted to the thread).

being retired, means never having to wait for the weekend.....

I do not think reading is the best approach to learning a programming language. My suggestion is to pick a task to do, then write a program for it.

For example:
1. use the editor to write this file:
Code:
<symbol>H</symbol> <name>Hydrogen</name>
<symbol>He</symbol> <name>Helium</name>

2. write a program to read the file
3. parse out the values.
4. print the list
