Frank,
Could you talk about this a little, please? I have not heard of the
interface.
DFSORT has an internal interface with DFSMSrmm, and an externalized
interface (ICETPEX) that other tape management systems are using. Here's a

dynamic work files ie 2 or 3. Does sort allocate multi volume files if they
need to be very large for a very big sort.

Ed,
Doesn't a 6250 reel tape only hold about 30MB of data, so you were sorting
about 750MB? Working on SORTWKnn must total twice your input file you are
talking three SORTWKnn of about 500MB.
I can't imagine why it would be such a hard thing to figure out...

Thanks for mentioning that.

None, RLSE only works with QSAM/BSAM output files and sortwknn files are
never really initialized.
