Food for thought. zEDC is block oriented rather than record oriented (i.e. reads/writes full track blocks on DASD and BLKSIZE become logical (i.e. the size of the buffer used to exchange data with the application)), so any processing that expects to make use of BLKSIZE to perform physical I/O (random, update, etc) will fail.

Thus DFSORT will have issues for SORTWK datasets, but not SORTIN/SORTOUT datasets.

Dave,

Can you elaborate more on the issue that you have with DFSORT as ZEDC is supported by DFSORT. You can send an offline mail to avoid the clutter here.

Thanks,
