CARD(x)
WORD(x)

x: iexp

BYTE() returns the lower 8 bits of the numerical expression x.

The functions CARD() returns the lower 16 bits of the numerical expression x.

The function WORD() extends a word to long word length (32 bits) by copying bit
15 to bit positions 16 to 31, thus preserving the sign.

Examples:

    PRINT BYTE(255),BYTE(1+255)
    PRINT HEX$(CARD(&H1234ABCD))

--> 255, 0, and ABCD are printed.

    x%=&HFFFF
    PRINT BIN$(x%,32)
    x%=WORD(x%)
    PRINT BIN$(x%,32)
