System.ArrayType - Manhunter07/MFL GitHub Wiki
Declaration
const ArrayType = 5
Description
The ArrayType constant in the System package represents the type code for arrays of any length and depth. It is returned when retrieving the type of such any array value using the TypeOf function.
Remarks
Other than the name might suggest, it is not a type but a constant. If you want to restrict function parameters to accept arrays only, use the array type constructor instead.
