I generally prefer to unallocate by DDNAME rather than by DSNAME,
since if the data set is allocated multiple times freeing all
the DDNAMEs may be an unintended consequence.  I understand that
various IBM software has suffered from this defect; I don't
know any current examples.  A utility shouldn't FREE anything
it didn't ALLOCATE; it shouldn't leave anything ALLOCATEd that
was FREEd before it was called.

(But I recognize the OP asked how to unallocate a Dataset, not
a DDNAME.)
