What does RND 2-3 do? In standard BASICs, RND generates a random number in the range [0,1) but the 2-3 would be a syntax error.

If RND takes a single parameter I'd assume it would probably parse as
X +( 2*RND(2)) -3
On an interpreter where built-ins like RND do not need parentheses (pending verification on your selected interpreter)

But every basic is different so it needs checking.

It's IF POINT(X, Y) NEXT Y
that has my confused.

Whilst coding Python on a handheld isn't easy*, it is much easier than writing 3 different basic solutions, and trying to key those in on 3 different calculators each with their own idiosyncrasies.
