Used to perform a logical exclusion on two expressions.
Syntax
result = expression1 Xor expression2

The Xor operator syntax has these parts:

Part Description
result Any numeric variable.
expression1 Any expression.
expression2 Any expression.

Remarks
If one, and only one, of the expressions evaluates to True, result is True. However, if either expression is Null, result is also Null. When neither expression is Null, result is determined according to the following table:

If expression1 is And expression2 is Then result is
True True False
True False True
False True True
False False False
The Xor operator also performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:

If bit in expression1 is And bit in expression2 is Then result is
0 0 0
0 1 1
1 0 1
1 1 0
