Xor Operator

Microsoft® Visual Basic® Scripting Edition
Xor Operator

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
