Note:
This example calculates the cube if
x
|
0
; otherwise, it returns a
0

The argument x is automatically treated as a local variable. However, if the example
needed another variable, the function would need to declare it as local by using the
Local command.
There is an implied
Return
at the end of the function. If the last line is not an expression,
an error occurs.
