I would like to see an example of DEF FUNC usage; I'm specifically interested in understanding how to return a value from a function call.

You can use RETURN value, to return values from functions, or assign the function name a value when exiting the function. Using RETURN returns the value and then exits the function immediately.

Here is a RETURN example.
This one just returns the number 5, exiting the function.

-----------------------

Print return5

def return5
return 5
Print "this won't show because return used above"
end def

------------------


This function accepts parameters and returns them after using them. It will combine two strings. The function name is assigned a value. Without using RETURN, the function code continues until END DEF.

--------------------

Print combine$("hello ", "world!")

def combine$(first$, second$)
combine$=first$ & second$
'Print "This would show if I wasn't commented out"
End def

-------------------

Hope that helps.
