There is no "z/OS only" tool to do this. However, somewhere on the CBTTAPE is a program call DMOD (sorry, don't have a file reference) that will do this. I last used this in the late 90's and it worked then. It will obviously need to be reassembled with the current macros.
HTH, <snip> Say you have many PDS(not PDSE) datasets that for whatever reason were never allocated with secondary extents(not LLA datasets). Is there a tool that can change the dataset secondary allocation from 0 to some other number easily? Don't want to have to reallocate the datasets. I don't see that the PDS can do it, nor does it look like IDCAMS can do it... </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
