Syntax

expr1 Xor expr2

Elements

expr1, expr2

Any expressions. Their values must lie within the range for Long values.

The following table explains how LotusScript determines the result of the Xor operation.

expr1	expr2	Result
TRUE	TRUE	FALSE
TRUE	FALSE	TRUE
FALSE	TRUE	TRUE
FALSE	FALSE	FALSE
TRUE	NULL	NULL
NULL	TRUE	NULL
FALSE	NULL	NULL
NULL	FALSE	NULL
NULL	NULL	NULL

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 expr1	Bit 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
