| > | increment the data pointer (to point to the next cell to the right). |
| < | decrement the data pointer (to point to the next cell to the left). |
| + | increment (increase by one) the byte at the data pointer. |
| - | decrement (decrease by one) the byte at the data pointer. |
| . | output the byte at the data pointer. |
| , | accept one byte of input, storing its value in the byte at the data pointer. |
| [ | if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. |
| ] | if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command. |
