Re: Recursive Subprocedure help.

Hi Michael,

I thought that the parm list was local to the call level? So that when
return from the recursive call, your parm list hadn't changed in the
instance?

That'd be true if you're passing the contents by value. (i.e. with the VALUE d-spec keyword on your prototype)


When I returned back to the first instance the parm variable was the value
of the last instance.

Sounds like you're passing by reference.


I obviously thought I was okay with using the parms in the procedure, but I
guess I need to move them to local variables in the produce.

Produce? Do you mean procedure? heh... bugs in a procedure are one thing, bugs in produce are quite another :)

Anyway, what you really need is to understand the difference between passing by reference and passing by value, and use the correct one for what you're doing.
