[vb6] VarType function determines what is contained in a variant

The VB VarType function is the way for determining what type of data is contained in a variant variable, if it is an array and of which type. For example:

    Dim Barray(20) As Byte
    Dim MyVariant as Variant
    MyVariant = Barray
    Return = VarType(MyVariant)

"Return" turns out to be equal to vbArray Or vbByte.
