X or (operator)

 Syntax expression1 Xor expression2 Description Performs a logical or binary exclusion on two expressions. Comments If both expressions are either Boolean, Boolean variants, or NULL variants, then a logical exclusion is performed as follows: If the first expression is and the second expression is then the result is TRUE TRUE FALSE TRUE FALSE TRUE FALSE TRUE TRUE FALSE FALSE FALSE If either expression is Null, then Null is returned. Binary Exclusion If the two expressions are Integer, then a binary exclusion is performed, returning an Integer result. All other numeric types (including Empty variants) are converted to Long, and a binary exclusion is then performed, returning a Long result. Binary exclusion forms a new value based on a bit-by-bit comparison of the binary representations of the two expressions according to the following table:
 1 Xor 1 = 0 Example 0 Xor 1 = 1 5 01101001 1 Xor 0 = 1 6 10101010 0 Xor 0 = 0 Xor  11000011 Example This example builds a logic table for the XOR function and displays it. Const crlf = Chr\$(13) + Chr\$(10) Sub Main()   msg1 = "Logic table for Xor:" & crlf & crlf   For x = -1 To 0     For y = -1 To 0       z = x Xor y       msg1 = msg1 & CBool(x) & " Xor "       msg1 = msg1 & CBool(y) & " = "       msg1 = msg1 & CBool(z) & crlf     Next y   Next x   MsgBox msg1 End Sub See Also Operator Precedence (topic); Or (operator); Eqv (operator); Imp (operator); And (operator).
