I elided too much, and I believe you exploited the omission. This thread
(had) concerned nested procedure calls. I believe I've been told that
there's no construct such as:
<unique stepname>.<procstepname>.<subprocstepname>
.. so how does one unambiguously identify steps at the second, etc., level
of procedure calls? I believe you have misrepresented a solution to a
restricted subset of the problem as a solution to the general problem.
Your CS 101 example would not be correct if the syntax of the language
restricted qualified names to two qualifiers but allowed structures to
be declared to three and more levels as JCL has naively done.
