name [ ( [ * rank ] ) ] [ As type | In unit ] ByRef- Optional modifier (short for "by reference") lets the passed argument have its value changed by the procedure. Thus the parameter becomes an alias of the argument. Without this, the parameter is a copy of the argument. But objects and arrays are always passed by reference.

rank- Optional integer literal. Specifies the number of dimensions of the passed array.
type- Optional data type
unit- Optional unit of measure
default_value- Optional constant of a type compatible with
