View Ref-Filex IMP y

x, y: iexp

The operator IMP (Implication) corresponds to a logical consequence. The result
is only FALSE if a FALSE expression follows a TRUE one. IMP also works at the
bit level. Unlike AND, OR, XOR, and EQV, the sequence of the arguments is
important.

    x | y | x IMP y
    --|---|--------
    T | T | T
    T | F | F
    F | T | T
    F | F | T

Examples:

    PRINT TRUE IMP -1
    PRINT 0 IMP FALSE
    PRINT TRUE IMP 0

--> The numbers -1, -1 and, 0 appear on the screen.

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

--> Displays 0011, 1010, and 1110 on the screen.
