Forgive me, Harlan, for failing to see how using the common meaning of "array
formula" - a function that requires array entry (CSE) to work - is any different that
what you're saying....

You're confusing 'formula' and 'function'. There are array formulas
that involve NO function calls. That is, formulas don't require
functions, but functions serve no purpose outside formulas.

If you still don't understand the difference, not much more I can say.
