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

                        be Cell #1 which was cleared by the previous loop

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
