Function() As Type / End Function

Function name(parameter As Type, …) As Type

Note: Each function has its own scope.

A function is declared using the

Function() statement. The parentheses may contain one or more optional parameters;

parameters can also have default values and expressions.

The type of each parameter may be declared. The return type of the function may also be declared. If a parameter type or
return type is not declared, it is Dynamic by default. Intrinsic types are passed by value (and a copy is made), while
objects are passed by reference. The

Sub statement can be used instead of Function as a shortcut for creating a

function with return type Void.

A parameter can be one of the following types:

•

Integer

•

Float

•

Double

•

String

•

Object

•

Dynamic

The function return can be one of the following types:

•

Void
