View Ref-Filex XOR y

x, y: iexp

The XOR operator produces the value TRUE if one, but not both, of the arguments
is TRUE. If they are both TRUE, or both FALSE, the result is FALSE.

Unlike OR, where TRUE OR TRUE = TRUE, TRUE XOR TRUE = FALSE. (XOR is the
Boolean Exclusive Disjunction operation.)

Again, XOR works individually on each of the 32 bits of numeric arguments.

    x | y | x XOR y
    --|---|--------
    T | T | F
    T | F | T
    F | T | T
    F | F | F

Examples:

    PRINT FALSE XOR -1
    PRINT -1 XOR 1
    PRINT 0 XOR FALSE

--> The numbers -1, -2, and 0 are printed on the screen.

    x=3
    y=10
    PRINT BIN$(x,4)
    PRINT BIN$(y,4)
    PRINT BIN$(x XOR y,4),x XOR y

--> Displays 0011, 1010, 1001, and 9 on the screen.
