Passing by reference

From: Kras Kresh (

Is passing by reference even possible on circle?
I have a recursive function that needs to increment a memory location for
each call that does something.
I was successful in making it work by adding a global variable.
But, I'm wondering how I can pass by reference because I can't seem to be
able to.
Passing by reference will make much more sense just in case of a screwup
somewhere in the code. It doesn't make much sense to leave this variable
lying around useless.
