        Function {\em fun\_eq()} is called when opcode {\em op\_eq} is read.
        This function pops two variables, calls {\em compare()} to compare the
        values, and pushes the result of the comparison. The two compared
        variables are discarded.

        The result of the comparison is logically {\em not}-ted when two
        integers are beging compared, since {\em compare()} subtracts two
        integer values as result.
