Googled for some of the abends and this site came up.

East or West, India is the best!

Thank you.

Many sites have standard jobs to define their GDGs.

I was asking why would we delete a GDG base and then again recreate it? We should just keep the base intact when we require it again.

How have you managed to copy the GDG base with same properties again?

Hi Robert,

I hve used the following:

Code: Select all

//PGM EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE (YOUR.INPUT.GDG) GDG

But it gave me RC=8. Then I tried:

Code: Select all

//PGM EXEC PGM=IEFBR14
//GDGB DD DSN=YOUR.INPUT.GDG,
// DISP=(OLD,DELETE,DELETE)

It deleted all versions of it. Which one is better?

Hi,

Which Technology you are talking about? For mainframe they have only insurance related projects and there are different projects. I have known people from there but I have not worked there myself.

Hi,

Can someone please advise me if we can delete all versions of a GDG and just keep base of it. I tried to delete them using ISPF 3.4, locating and deleting them one by one for test. But is there a way to do it using some program or utility? Please advise.

Thanks.

Thanks. When we use WHEN=INIT, does it mean to go to the initial record in the file or in the "GROUP"? Please advise me on this.

Thanks Robert and William for the great explanations you put it. really appreciate your time. As Robert said, "An index is a pointer that contains the address of the array element" and William said, "An index does not contain an address. It just contains the displacement of an element...

Hi,

What is the main difference between Index and subscript? I read some differences about them online but they are confusing. Can someone please brief them in a layman language.
