return values with a function

hi...can someone point me to info on an example of returning a value with a function....I found how to pass a function a value but how does you use the value returned by a function?

thanks
Dan

Action: Function:Set return value

Expression: Function:ReturnValue

manual

thanks!...but when I create a function with local variable inside of it, why wont it let me select one of those local variables as a return value?
thanks

oh ok....thanks!

easier would be (using blackhornet's example)

set text to function.call("MyFnc")

combines the two lines into one
