And that is a good thing, isn't it? You don't want everybody to create deadlocks, only APF programmers. There are 2 options: 1 Retry the allocation at some interval, for some period. SAS has the ability for this in the FILENAME/LIBNAME statement. Dynalloc coders have it too of course. 2 Return to JCL allocation. This will very much clear up the situation: -The programmer does not have to worry about allocation, when the program runs, it *has* the dataset. -Jobs will simply wait and produce message for the operator, who can then determine who is waiting and who is holding and what to do with the situaition. The messages can also be trapped by your automation tool, which can then do the determination and consequent actions.
