HP49-50G: help for recursive

[Gil]

Thanks for your suggestion.

It's left arrow.

I would have rather used such a variable.

« -> x
«
IFERR '<-max' RCL
THEN x ->
<-max
«
»
ELSE DROP
END <-max
»
»

What I then need is the <—max variable outside the IF... THEN... END structure.

But as the red «» are closed, the <—max after the END vanishes, creating logically an error, having finished its job, unless another program is called internally.
But putting <—max inside the red «» means that a lot will also have to be inside the red «».

Not that easy to solve properly — for me, at least.
