Character Instruction Performed

• > Increment the data pointer by one (to point to the next cell to the right).
• < Decrement the data pointer by one (to point to the next cell to the left). Undefined if at 0.
• + Increment the byte at the data pointer by one modulo 256.
• - Decrement the byte at the data pointer by one modulo 256.
• . 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.
