You can't. It exists as it exists.

You could use SORT or ICETOOL or ICEGENER to reformat the records and then recreate the GDG version.

By 'length of a GDG' I assume you mean the number of entries, as in the LIMIT(nnn) used when the GDG was built.

Do This:

Via SPF 3.4, display the GDG base.

Then OVERTYPE the line that contains the GDG BASE with this:


ALTER / LIMIT(nnn)


where nnn is the desired number of entries.

This assumes that nnn is greater than the number originally used. If you want to make the number lower, then delete all the entries you do not want and then do the ALTER.



You can accomplish the same via IDCAMS in batch.

Hi Bruce,

I don't think this was what reddy307 asked for.

By length, what i would dare to guess is the LRECL of the GDG generation..

Coz i don't think anybody wil ask to change the limits of CURRENT GENERATION of a gdg... icon_smile.gif
