        <textarea id="code" name="code"> [ This program prints "Hello World!" and a newline to the screen, its length is 106 active command characters [it is not the shortest.] This loop is a "comment loop", it's a simple way of adding a comment to a BF program such that you don't have

            to worry about any command characters. Any ".", ",", "+", "-", "<" and ">" characters are simply ignored, the "[" and "]" characters just have to be balanced. ] +++++ +++ Set Cell #0 to 8 [ >++++ Add 4 to Cell #1; this will always

            set Cell #1 to 4 [ as the cell will be cleared by the loop >++ Add 2 to Cell #2 >+++ Add 3 to Cell #3 >+++ Add 3 to Cell #4 >+ Add 1 to Cell #5 <<<<- Decrement the loop counter in Cell #1 ] Loop till Cell #1 is zero;

            number of iterations is 4 >+ Add 1 to Cell #2 >+ Add 1 to Cell #3 >- Subtract 1 from Cell #4 >>+ Add 1 to Cell #6 [<] 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' &gt;&gt;+. Add 1 to Cell #5 gives us an exclamation point &gt;++. And finally a newline from Cell #6 </textarea>
