Description

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
