There is much bias in English and Computer Science in the distinction
as well. The term `iterate' is much more common than `recur'.
Too many iteration-loving Comp-Sci types still disparage recursion,
and languages which either support or promote recursion.

Yes, this is the crux of it.
BTW Mathematicians use this concept too ... and linguists.
Recursive definitions are generally given higher status and
standing than non-recursive ones ... and for good reason.

The original question specified the use of recursion to produce
the side-effects known as squares.
The person posing the question has posed 3 questions involving
recursion.
Brian Harvey covered recursion in his "Computer Science Logo Style"
series in 3 chapters.
As it is on-line for free, I see no reason why those
interested in doing recursion in Logo just can't
access and read his rather well-written text ... and
be done with it.
