        !             4: ordered.  It reads in a file, without throwing away the existing buffer.
        !             5: So, for example,

        !            11: write the combined stuff on "both".  Try that, with those names,

        !            26: placed in water, forces cause the water to rise in the tube to a

        !            30: you show that this rise is not due to atmospheric pressure?
