115 | |||
116 | This loop is an "initial comment loop", a simple way of adding a comment | ||
117 | to a BF program such that you don't have to worry about any command | ||
118 | characters. Any ".", ",", "+", "-", "<" and ">" characters are simply | ||
119 | ignored, the "[" and "]" characters just have to be balanced. This | ||
120 | loop and the commands it contains are ignored because the current cell | ||
121 | defaults to a value of 0; the 0 value causes this loop to be skipped. | ||
