END FUNCTION
 
    - name             The name of the function and the data type it returns,
                       specified by a data-type suffix (%, &, !, #, or $).
    - parameterlist    One or more variables that specify parameters to be
                       passed to the function when it is called:
 
                       variable[( )] [AS type] [, variable[( )] [AS type]]...
 
                       variable    A Basic variable name.
                       type        The data type of the variable (INTEGER,
                                   LONG, SINGLE, DOUBLE, STRING, or a
                                   user-defined data type).
 
    - STATIC           Specifies that the values of the function's local
                       variables are saved between function calls.
    - expression       The return value of the function.
 
    - When you call the function, you can specify that an argument's value
      will not be changed by the function by enclosing the argument in
      parentheses.
