Hi ALL.
I must to get all volumes on which a specified dataset is resided.
Earlier I used the IGGCSI00 call with 'VOLSER' field specified. But this way is very slow for my tasks.

Recently I've got a suggestion to use LOCATE/CAMLST macros. But they allows to get only first 20 volumes of dataset and I did not find in doc how gets other volumes.

Can anybody suggest how can I get other volumes by LOCATE or give me another ways?

I'm using assembler and C and writing under MVS.

More thanks,
Igor Klingen

Igor Klingen,

Can't you use IEHLIST? Check this link for a detailed explanation of IEHLIST

Hope this helps...

Cheers

Kolusu, thank for answer.

If I will be use IEHLIST I must run this utility and then parse it sysout to get volume names. I think that it way will more long instead of IGGCSI00.

Thanks,

IGGCSIxx uses superlocate which is an extended form of the same SVC 26 that camlst locate uses. It is probably as fast as you will get. Is the slowness in the SVC 26 or in the parsing of the output?
