Hi all,

Please let me know the command/Function to get the current PDS name in which the executing rexx routine is stored.

Example: F5748TGH.CESOD.CHECKSTD.TOOL (COBSTDTL) is PDS with the member mentioned in parentheses. While executing the COBSTDTL (REXX routine) the DSN name F5748TGH.CESOD.CHECKSTD.TOOL is needed in the REXX Routine COBSTDTL.

Please let me know the command/function to acheive the above.

Thanks,
P.Senthil Prabhu.

You will need to chase the z/OS control blocks to get the dataset name, and even then it may not give you what you want as the SYSEXEC DD is likeley to contain a concatenation of libraries.

Are you running in batch or online ?
And why do you need to know the dataset name where the member resides ?

try "parse . . . . invdsn ."
dsname should be returned in variable invdsn

Parsing SOURCE only gives the member name - not the name of the PDS that the member is in. But, if you not executing a member it does give the PS file name.

sorry you are right I forgot the keyword source should have been
"parse source . . . . invdsn ."
However tried it here on various flavours of z/OS and it returns the dsname for a PDS

Doesn't work in batch returns ??? instead of dsname

I tried in TSO and batch - both times just got member name. When I converted to a PS file I got the file name. Maybe it is an installation setting that decides how much info you get and when? We are z/OS something or other.

Hi TSO ISRDDN.

This Service lists all the PDS that are supporting your current TSO SESSION.

I was going to ask what was wrong with the solutions given by the link provided by kolusu. The ISREDIT bits have always worked well for me in the past.

It seems that the OP hasn't responded since then, so I guess they must have found the solution.
