When I've had a need to move 3390 volume images to another data center,
I've used CMSDDR to dump them to files, then transferred the files via
either RSCS or ISFC. CMSDDR does some sort of packing on the files it
creates. Empty 3390-3's result in far smaller output files than full
ones do.

Well maybe if I could get PIPEDDR to work to the remote IP (my network
guys and I disagree a bit here, my problem not yours) then maybe I'd
shutup about TERSE. I have a need to do exacatly what you mentioned
'transfer complete 3390s from one data centre to another'. A rare but
PITA occurance. I was under the, maybe false, impresion that TERSE would
do a better job of compression than PACK. It might simply be a 'the
grass is greener' syndrom.
I'll probably be happy once I can get it working...
My thanks to the author for writing it and placing it on the download
page...
You wouldn't be willing to share your READER/URO mods would you? please
please..

Greetings Listers,
PIPEDDR can use TERSE or PACK stages for compression or use
no compression.. It only fails if TERSE option is specified
and the stage is not available. It is written so it does not
rely on TERSE
I have used PIPEDDR with PACK option to transfer complete
3390s from one data centre to another and it works well. It
saved the delay of waiting for a courier to take a
cartridge.
Just an aside, I thought I would update the code so it used
standard PIPES but when I did that TCPIP packets were lost.
Maybe TCPCLIENT and TCPLISTEN have different code or maybe I
screwed it up or maybe it was timing.
Another aside. Thanks to the author Bruce Hayden publishing
the code I was able to use PIPEDDR as a model and instead of
using TRACKREAD and TRACKWRITE to read and write dasd I used
READER and URO to read and write spool making a very simple
NJETCP link.
Cheers Graeme
