View Ref-Filex AND y

x, y: iexp

The logical operator AND (conjunction) checks whether two logical expressions x
and y are both true. Only in this case it produces the value TRUE (-1). If one
or both logical expressions are wrong, then AND produces a logical FALSE. With
AND each pair of the 32 bits is tested independently.

    x | y | x AND y
    --|---|--------
    T | T | T
    T | F | F
    F | T | F
    F | F | F

Examples:

    PRINT TRUE AND -1
    PRINT FALSE AND TRUE

--> On the screen the numbers -1 and 0 appear.

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

--> Displays 0011, 1010, 0010, and 2 on the screen.
