Jay - I guess
Yes indeed - my spell check - upon which my wayward fingers rely a great
deal - didn't catch that - but then it wouldn't would it?

Freudian slip?

Since you are something of a "Johnny come lately" - sorry, I couldn't
resist that - it's idiomatic for a newcomer - you won't, like all the grey
beards on the list, remember the "Program Logic Manual" available usually
with a "Y" letter - in place of "C" or "A" - for licenced users of a
software product.
Supposedly it contained sufficient information abort the product that the
folk responsible for diagnosing problems with the product could get a
handle on what was wrong.
Indeed it was also useful for people really to understand their product
since the regular manuals never seemed to have sufficient information to
get the best out of the product - or alternatively just knowing the raw
logic avoided the misunderstandings/ambiguities propagated by the authors
of the regular manuals.
I haven't been looking for any such manuals lately but I guess they have
become a "thing of the past". The nearest equivalent these days I suppose
is the generic "Diagnosis" manual.
Whether or not even a regular manual contains control block relationship
diagrams is a matter for the manual author and the developers who feed
him/her their stuff. Thus it's not guaranteed that any "service" manual
actually will contain such diagrams although probably they should.
In presenting troublesome operands - naturally I have NCP in mind - I have
even had to construct such diagrams from the text descriptions of control
blocks - so, if you want a better picture, you can get out a paper and
pencil. <g> I just happen to be reminded of this lately having rediscovered
these diagrams in a presentation while researching another thread.
Incidentally, I hope you are aware that "core dump" means a dump of the
system storage where the "core" refers to an ancient technology for
computer storage.
