AFAIK, one can only make DFSORT run worse, not better than it would do by itself. E.g. we had several problems with users that were experimenting with number and sizes of SORTWKs and other parameters in order to get jobs running reliably and these problems were usually solved by allowing DFSORT to make its own calculations of memory, memobjects, hiper/dataspaces and sortwks. I hope David Betten cares to elaborate on this. Kees ******************************************************** For information, services and offers, please visit our web site: http://www.klm.com.
