In addition to performing a logical exclusion, the Xor operator compares identically positioned bits in two numeric expressions (known as a bit-wise comparison) and sets the corresponding bit in the result according to the following table.
Bit n in expr1Bit n in expr2 Bit n in result
1 1 0
1 0 1
0 1 1
0 0 0

Example

' Boolean usage
Dim johnIsHere As Boolean, jimIsHere As Boolean

Dim oneButNotBothIsHere As Boolean

johnIsHere = TRUE

jimIsHere = FALSE

oneButNotBothIsHere = johnIsHere Xor jimIsHere

Print oneButNotBothIsHere         ' Prints True

' Bit-wise usage
Dim z As Integer, y As Integer
z% = &b11110000
y% = &b11001100
Print Bin$(z% Xor y%)              ' Prints 111100
