View Ref-Filex OR y

x, y: iexp

The command OR (disjunction) checks whether at least one of two logical
expressions x and y is TRUE. Only if x and y are both FALSE will the result
FALSE be produced. Unlike XOR, (see below) a TRUE result from OR means that one
or both arguments are TRUE. OR also works at the bit level with numbers.

    x | y | x OR y
   ---|---|-------
    T | T | T
    T | F | T
    F | T | T
    F | F | F

Examples:

    PRINT TRUE OR -1
    PRINT FALSE OR TRUE
    PRINT 0 OR FALSE

--> The numbers -1, -1, and 0 are displayed.

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

--> Displays 0011, 1010, 1011, and the number 11 appear on the screen.
