All these Operators work arithmetically: E.g. Not &H01 = &Hfe. Both values are evaluated to
true in an If expression. This is different to a logical Not operator, where Not &H01 = &H00.
4.3.5.3 Bit-Shift Operators
Bit-Shift operators are only allowed for Integer data types. With a Bit-Shift operation a 0 will always
be moved into one end.
