How to increase the LRECL of existing member?

Hi,

I have 10 members in one PDS. It has record length of 80. I want to change the record length of only one member of that PDS say from 80 to 200. Kindly let me know using which utility we can acheive this.

If this is a flat file, using IEBGENER, IDCAMS we can do this. But i want to change only one member in that PDS.

Thanks!

Hi Meenakshi,

Its not possible to increase the record length for a particular member(s) in PDS once the LRECL is defined.

Alternate/Only option is create a PDS with LRECL=200

Thanks

Hello,

ALL of the members in one pds need to be the same length.

Is this a serious question from a senior software engineer? I hope the TS is not working at a nuclear plant.

Just to pile on a bit - LRECL is a dataset attribute, and PDS members are not datasets.

Meenakshi Selvaraj,

There is something you can do however you must then rebuild your PDS to a new library then create that new member.

Merely allocate your new PDS with RECFM=VB along with something like LRECL=256. Copy the old library to the new one and all will be as it was and the new member can be up to 252 bytes. I do it sometimes with SAS code.

dick,

>>If a new length is needed for "one" member, changing the length/recfm of the PDS may cause Many abends . . .

Just once.

>>Possibly i misunderstand.

I think we're talking at cross purposes. Meenakshi claims to need a different LRECL for one member of a PDS with a different LRECL. By merely rebuilding it with a varible blocked PDS then I think his problem will be solved.

Try it. It works. Trust me.

Personally I believe his premise is shaky however this will work. Also of course it depends on the contents of the members. I have a feeling he really needs to have 2 distinct types of libraries.

Why not create a second pds with lrecl=200?

Move those members there.

Nice and neat: PDS.LRECL80 and PDS.LRECL200

No question about what is what and what is where.

That would be my solution.

dave,

>>Why not create a second pds with lrecl=200?

It's just one member that he seems to need however by rights programmers do need multiple libraries because those members have different functions - JCL, high-level program code, utilities, load libraries and control cards.

Personally I think he indeed needs a new library or seemingly a sequential file as LRECL=200 seems odd.
