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.
