Well the deletion of all members of a PDS DFSORT trick is written when IDCAMS did not support the Wild card deletion function on PDS members. So DFSORT chose the traditional method of deleting the members. The new features are written based on the customers needs and if a customer is upto date with the latest features then he can use IDCAMS wild card deletion. We just keep on adding new tricks of DFSORT and never delete off any trick from that document. Similarly DFSORT had another trick of reading GDG generations in FIFO order and with z/OS 2.1 the system itself supports the FIFO parm. So the new enhancements gives you an alternative solution and the customer is wise to chose the optimal solution. >>>Does it at least sort the list in descending order? Descending order of what? member names or Size? Why exactly do you need to sort the list ? Do you think it would make a difference to the directory blocks? And just for the record as DFSORT is capable of sorting the member names in either ascending/descending order.

It builds a list of IDCAMS commands to delete the members one-by-one. Now that there are better techniques, it becomes less smart. Does it at least sort the list in descending order?
