I think what you're seeing is quite simply a bug.
Parameters are passed by ref as you say, but the value types (String, 
Number, Boolean) are immutable - any operations on them produce new 
values rather than change the object state.
The current interpretor uses a simple stack mechanism whereby the 
variables currently in scope are 'hidden' when a function call is made. 
It should be done the same way for procedure calls. Instead it seems 
the recursive procedure call sets the same 'number' variable that is 
already being used.

I'm currently doing some deep compiler refactoring for the next 
version, I'll fit in a fix for this. If you can, pls report the problem 
on bugzilla:

thanks Christophe, speak more soon!
