define questions

[AlexFekken]

My C is a bit rusty, but I am sure even in C you would get the same behaviour if you create functions with a "standard" 'int x' parameter. You would need to pass the argument by reference (define the parameter as 'int &x') to increment it. I don't think you can do that on the Prime, but I am happy to be corrected.

If I had a guess then I'd say perhaps you have a Java background where everything is an object and passed by reference. :-)
