GDG's version

Hi,

If I have a GDG index with model parameter of (Recfm=FB,Lrecl=80,Blksize=800), can I create a GDG version with the following attributes:

Case1:

(Recfm=FB,Lrecl=150,Blksize=1500)

Case2:

(Recfm=VB,Lrecl=150,Blksize=1500)

The GDG base is not defined with a model parameter. You can define each generation with a different set of characteristics if you want. And you can do that when creating a new version as well. It's not clear whether you want version or generation since they are both part of a GDG and have extremely different meanings.

Apologies for the confusion.

Actually I meant generations and not versions.

Yes each generation has it's own DCB characteristics, but this could cause problems if there is a need to process all generations.

One out of thread (box

) query is here: as we know, each generation has it's own DCB characteristics, but why IBM allowed this? While all of them are chronologically linked to each other.

Hi Anuj,

Many times the system will not only permit one to shoot oneself in the foot, but will also load the gun. . . .

At least this can be controlled if one is so inclined
