Way to change the LRECL of all existing generations of GDG?

[G Mishra]

Hi,

I need to change the LRECL of a file from 100 to 300 bytes. We'd need to change the programtoo later. We have also modified the JCLs for new LRECL. But how do I care about the existing generations, they 100 bytes. Is there any way to change the file length of all generations of GDG?

Hi Mishra,

First could you tell me , How will you fill the contents of 300 bytes for all old generations?

Copy them using whatever method you wish. You may need a program if the the data needs re-arranging although IEB/ICEGENER could do that for you.

SPACES will be used.

Thanks nicc but method is what I'm trying to figure out. Will IEBGENER allow to increase the lenght with a single step? I think, I'd need to copy as many steps as many GDGs are there...
