Documentation
The complete BF language:
- > Increment the pointer.
- < Decrement the pointer.
- + Increment the byte at the pointer.
- - Decrement the byte at the pointer.
- . Output the byte at the pointer.
- , Input a byte and store it in the byte at the pointer.
- [ Jump forward past the matching ] if the byte at the pointer is zero.
- ] Jump backward to the matching [ unless the byte at the pointer is zero.
