exactly! The brainfuck execution starts with the pointer at the first byte of zero-filled array:

So the first ">" in my program moves the pointer to the next byte, and this skipped first byte would serve as a stopper when pointer moves back.

Ah. I wasn't aware of that part of the spec. In that case, then, the code would work.

It's an interesting language, and one that I'm not convinced is so entirely without practical application as is commonly stated.
