HP49-50G: help for recursive

[Gjermund Skailand]

Hi,

Not sure if this solves your case
but at least to avoid global variable 'max' you could use a
"compiled local variable", that is, a local variable with first character is an arrow (left or right) I don't remember, but is is in the (advanced) user guide.
Those variables are accessible to subsequent calls.
