Russell and others,

I guess I wasnt too clear in what I was after. 

Firstly, the tool to copy the tape must be FREE. I know there are good
vendor tools to do what I want, but this site isnt going to spend any money
on getting them. 

Secondly, I would like to copy the entire tape as-is. Basically tell the
utility to "duplicate this tape". Many of the files on the source tape are
256K. I don't want to reblock them. I would prefer to maintain expiry date
info and have RMM's VRS control expiration. I don't care that the datasets
will not get cataloged.

I know I can IEBGENER etc individual files to a new tape. But on the 1 TB
raw capacity tapes we are using, we have 5,000 files and more on a tape, and
I would prefer not to have to code JCL to copy each of those files! In the
absence of anything better, I will write REXX to create such JCL, using RMM
info about the tape datasets as the source.

I know that COPYMODS and related from the CBT Tape will do pretty much what
I want, but 64K blocksizes is as big as it handles, from what I read in
their doco.

We are RMM, but I don't know that this makes much difference.

Hoping for a miracle....

Regards, Fred Schmidt
