Flip Bit Function
Bitwise Class

Public Function FlipBit( _
      ByVal vValue As Variant _
    , ByVal vBit As Variant _
    ) As Variant

Perform the logical "Not" operation on one of the bits within a value.
Function uses the GetBit and SetBit functions; see them for details.

Truth table: 
    NOT
        +---
      0 | 1
      1 | 0
Examples: 
    FlipBit(0, 5) = 16
    FlipBit(-1, 5) = -17
    FlipBit(255, 5) = 239
    FlipBit("BC", 5) = "BS"

vValue: Value in which the Not operation will be performed on one of its bits. Function returns Null if vValue is Null.
vBit: The number of the bit on which the Not operation will be performed. Function returns Null if vBit is Null or cannot be fixed up to a number. Function returns Null if vBit is <= 0 (less than or equal to zero). Function returns Null if vBit is greater than the number of bits within the value vValue.
