Hi Apeksha,

| What it means by GDG model? Could you please explain? |
Before you can create the files that attach to a GDG base, you need to create a model dataset that contains the DCB information for the files. This model data just needs to be a VTOC entry, it does not need to actually use up disk space. It is possible to create a different model dataset for every possible DCB combination, and some sites actually do that, but this needs a lot of effort to maintain. Many sites use a single model dataset, and then override the DCB information to build the correct type of file. To create a model DCB, use a dummy IEFBR14 job like this
| Code: |
//STEP2 EXEC PGM=IEFBR14
//MODEL1 DD DSN=I.AM.GDG.MODEL,
// DISP=(NEW,KEEP,DELETE),
// UNIT=SYSDA,
// SPACE(TRK,0),
// DCB=(LRECL=80,RECFM=FB) |
The SPACE=(TRK,0) parameter means that this file will just be created as a VTOC entry, it will not use up disk space.
But as Dick & Expat has mentioned, just to quote again..

And as I said earlier I've never tried to create a GDG-model ever at my shop.
Hope this helps.. |

Hi,

| I have a silly question; Can anyone tell me that the GDG base is treated as a PDS or a PS? |
It should not be called either PDS or PS, that's why it's given a different name- GDG Base.
PS. Probably I also want a better explanation here.. |
