Just to clarify, DFSORT can cetrainly use more than the 1st extent, it just can't use multiple volumes. As long as DSNTYPE=LARGE is coded on the DD statement, each of the SORTWK DDs should be able to use multiple extents. Since a 3390-9 has a capacity of 10,017 cylinders, you should be able to get 3 extents of 3335 cylinders on each work data set if the volumes are empty.
