Ouch!  So if the system so "silently ignores" a data set containing a program 
object I
intended to use, but a later catenand contains an object similarly named but 
different
version, I'll execute the wrong version.

Terrible design.

o Hardly helps to add a dummy final step with DISP=SHR (OLD guarantees failure)
  because another job may have started to WAIT for that DSN.

o EXEC sorely needs explicit pathing (EXEC PGM=data.set.name(member), not
  merely the referback form).
