                FUNCTION UINT and PROTOTYPE
                   PARAMETERS VALUE UINT word1, VALUE UINT word2

        Description:
        ------------

                These functions implement three bitwise operations,
        Logical AND, OR, and XOR.  They each take two integer values,
        and perform their logical function upon the two.  The result
        of that operation is returned.

        For those of you not familiar with the logical operands, here's
        a table, in binary, so that you can see how they work.

            01001010            01001010                01001010
        AND 00001010         OR 00101010            XOR 00101010
            --------            --------                --------
            00001010            01101010                01100000

        If you can't figure it out, here it is in english:

        AND will test two bits at a time, one from each word.  The
        resulting bit will be 1 if the first bit AND the second bit
        are both 1.


                *- Examples:

                ? and( 1, 3 )   && prints 1, because 1 and 3 look like:
                                && 00000001 AND 00000011 ->
