uh....so can I return a value from a method....and if so how would it be done...?
I am attempting to use a global variable that will be sometimes passed to a method, messed with by the method and then returned to the main loop....
does this make sense?
aargh....my programming skills are rusty!

To return something from a method, the method must be of the same type as what it returns.
For example:
void doSomething() {whee;} returns nothing
int doSomething2() {whee; return 1;} returns an INT
String doSomething3() {whee; return "bucket";} returns a String
In your case, you could have something like so:
Code:
int GLOBALVARIABLE1 = 1
int addertron() {
return GLOBALVARIABLE += 2;
}

This really isn't the proper way to do it (for various reasons). So if you feel like it, you could make it a little 'better', and do it as follows:
Code:
int GLOBVAR1 = 1;
int addertron(int g) {
return g += 2;
}
GLOBVAR1 = addertron(GLOBVAR1);

If this doesn't make any sense, it's partially because I haven't slept yet, and I am therefore nonsensical. whee.

hey... thanks a lot....wow....and so quickly!
I think I actually got it....
of course it's not the answer I wanted for what I am trying to do, but that's okay.
