How to find the given DS is GDG or not using REXX

Pons

I just want to know the given dataset is GDG or Not.

I tried with SYSDSN and LISTDSI. Both are not working....

I gave the base GDG and tried with all the above options... Pls help me...

I'm devoloping a tool which will give the type of dataset.. If I give the GDG Base it should give the result as GDG....

Thanks.

Use the LISTCAT TSO/E Command.

Take a look at THIS thread. It should be easy enough to adapt the code to run from a terminal instead of in batch.

Hi Expat,

I got the below details form the given link. But i am not clear about this things. Can you please just give the code only which will tell the given dataset type...

Suppose if i give PDS dataset; it should tell PDS or
If i give GDG base it should tell GDG.

Can you please help me here....

The code for CSI is as follows. It should be much faster than your own code, and uses all of the standard wildcard combinations.

JCL Code:

//STEP0020 EXEC PGM=IKJEFT01,PARM='IGGCSIRX'
//SYSEXEC DD DSN=Your REXX Library,DISP=SHR
//SYSOUT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD DUMMY
//CATIN DD *
**
/*

The REXX code
Code:

/* REXX ** INVOKE CSI VIA BATCH REXX PROCESS */
"EXECIO * DISKR CATIN ( STEM CAT. FINIS"

What have YOU tried so far with the code that I had posted.
