|

|
|
[<] Move back to the first zero cell you find; this will
|
||
|
|
be Cell #1 which was cleared by the previous loop
|

|
] 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

>>. 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
