hi,
i am running a REXX program using a JCl .below is the part of jcl which i am using
"/STEP2 EXEC PGM=IRXJCL,PARM='MAINBATC'
//SYSEXEC DD DSN=IDF.REXX.COCOV.DAUG15.TARGO,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD DUMMY
//FILEI DD DSN=IDF.REXX.DAUG15.NEW(TESTPGM1),DISP=SHR "

now, Dataset specified(IDF.REXX.DAUG15.NEW(TESTPGM1)) in FILEI i have to get this DD in a Rexx Program...,

how to get this we have to use PARSE or is there any some other possible ways
please help me out guys...,;)

If you can change your job to run TSO batch, then the easiest solution would be to capture the output from a Address TSO 'LISTALC ST' and parse it. The output is not very friendly, but it is doable.

Simplest: I would pass it in like this:


Also, I think MAINBATC should have a programming interface. One of the requirements should be to use a specific DD name.

actually not clear on what you want -
- the dataset info for ddname FILEI ?
- a list of datasets allocated to your job?

in the first case you should look at the LISTDSI built-in REXX function, in the 2nd case see my previous reply

hi,
Thanks for the reply,

The main objective is this MAINBATC (which is a member of IDF.REXX.COCOV.DAUG15.TARGO) have rexx code it will take a pds(IDF.REXX.DAUG15.NEW(TESTPGM1)) as input file and perform some operation and after that it will write a report like thing to a output file
I am using this JCL above(its not the full JCL i have used its a part) and IRXJCL utility for executing MAINBATC
i want this input file IDF.REXX.DAUG15.NEW(TESTPGM1) to be stored in a variable in (MAINBATC) so that i can use this variable for a display purpose

If you simply want to read the file then use EXECIO e.g.

The dataset is already allocated via the JCL.

i want this input file IDF.REXX.DAUG15.NEW(TESTPGM1)

You will get better answers if you use more concise terms. Please use the terms DD name or data set name. In your example, the DD name is 'FILEI' and the data set name is 'IDF.REXX.DAUG15.NEW(TESTPGM1)'.

People get confused when you refer to a 'file'. Most people consider the DD name to be the file name. Some others think a file name refers to USS files.

Your problem is not entirely clear to me, but it seems as if you want the data set name associated with a given DD name. If so, would you not be better off running under background TSO and using the LISTDSI external function?

I agree with Akatsukami. Unless you have a very compelling reason not to use TSO batch I strongly suggest that you use that in general. It makes life so much easier.

It's easier to read tea leaves then to make sense of the gobbledygook of the TS...

Give us a clear description of what you want!
