The only "destructive move" I have been able to find (i.e, a real move,
not a copy) based on one real response, is in C (and derivatives) that
is not really what we are talking about.
It's move of a "change the pointer to the variable and drop the original
storage" type of thing. And, it's a function, not a verb. And, it
relates more to what happens to intermediate fields as they are used by
C and not programmer variables.
Bob, I understand your confusion, because I agree with you. Such a
language does not really exist. The excuse of "mv" vs. "cp" in linux is
not a valid example as those are file management commands, not data
manipulation verbs as used in programming languages.
And, to get back to the original statement by someone that Cobol is not
English because of the use of MOVE instead of COPY is just silly.

You may have done so - by now I don't remember who said what first :) - but I
was referring to Mr Crayford's post below. As I understood them, Tony Thigpen
wrote that a MOVE is actually a copy, and Mr Crayford disagreed. I'm confused;
is there any computer language in which the verb MOVE exists and doesn't
actually mean COPY?
...or SET, as you suggest. Yes, I like SET better.

I referred to this since someone said that COBOL is English like. As such
the language is wrong because it does not describe correctly in English
what happens. COPY, REPLICATE, PROPAGATE would all be more precise English.
IDEAL(CA/Broadcom) has MOVE and SET. They do the same thing. Which do you
prefer:
MOVE A TO B or
SET B = A ?

I beg to differ! For the programming languages I code in use there is a
huge difference between copy and move semantics.

From the start, MOVE in the programming world has been equated to what
you are calling a COPY.
