I won't call a BASIC interpreter trivial.

For example: how do you create
even modest (screen-oriented) editor without adding
several variables that reflect its state - where the
cursor is at the moment, what's the filename in use,
how are values of user's settings/preferences - all
that - etc. etc.?

Like I said - arrays are a different thing. But my repository holds a screen editor. It has two variables. Which screen and which position in that screen. Your trivial example holds three. One for parameter one,
one for parameter two and one for the result.
