I have a tape file with a standard user label written on it. I'm using a DFSORT job to copy the tape file onto another tape file. I find that the label information is not copied over. Is there a way to do this in DFSORT?

Cheers,
Coolman

Can I assume this as not possible? Frank, can you please confirm this

I really don't know anything about standard user labels. How do you create them? Does IEBGENER copy them? Perhaps there's something special you have to specify in the JCL to get them?

I talked to an IBMer who knows about standard user labels. He told me setting them up requires supplying exit code that OPEN can hook into. DFSORT does NOT have any way to hook in that kind of exit code. It appears that IEBGENER does, though, so you might be able to use IEBGENER to copy your standard user labels. Standard user labels are not really part of the data set per se. They're a separately managed "area" on the tape. (Maybe you knew all this.)

Frank,

Thanks for your prompt response. Yes, you are right in the fact that IEBGENER does copy user labels. But, IEBGENER fails when your I/P and O/P DCB parms don't match for which we looked up to SORT as our saviour. But SORT let us down as we were not able to copy user labels which was the limitation. I wanted to check this up with you before I give a go-down to my folks.

Appreciate your efforts over this.

Cheers,
Coolman.

Coolman,

Shortly, to do this you have to use BLP option in the label jcl card. As far as i remember DFSORT is unable to do this.
DITTO has a feature made for this kind of need : TT. You have to pay to use DITTO. Be aware that multi volumes are not supported by TT.

Hi Coolman,

It's been a Looong time since I've used SUL and BLP. You may be able to copy the Header label group and the trailers using BLP processing and sandwich the copied data between the 2 groups.

I've been in shops where BLP was not allowed. You may have to check w/your sysprogs.

The assumption is that your label exits used logic to create the original labels that is still valid for the copied file. For example, if you change the blksize on the O/P side of the sort and the exits used the blk count info in the trailer(s), that becomes problematic. Multi volume files also can present label problems when you're forced to copy the labels to the O/P file.

Taking this approach is risky if you don't know (or can't determine) the label ceation/checking logic used by the exits.

HTH, Jack.
