        [<]                 Move back to the first zero cell you find; this will

                            be Cell #1 which was cleared by the previous loop

        <-                  Decrement the loop Counter in Cell #0

    ]                       Loop till Cell #0 is zero; number of iterations is 8

     

    The result of this is:

    Cell No :   0   1   2   3   4   5   6

    Contents:   0   0  72 104  88  32   8

    Pointer :   ^

     

    >>.                     Cell #2 has value 72 which is 'H'

    >---.                   Subtract 3 from Cell #3 to get 101 which is 'e'

    +++++ ++..+++.          Likewise for 'llo' from Cell #3

    >>.                     Cell #5 is 32 for the space

    <-.                     Subtract 1 from Cell #4 for 87 to give a 'W'

    <.                      Cell #3 was set to 'o' from the end of 'Hello'

    +++.----- -.----- ---.  Cell #3 for 'rl' and 'd'

    >>+.                    Add 1 to Cell #5 gives us an exclamation point

    >++.                    And finally a newline from Cell #6
