Boink

Boink is a language with 1 command by User:Hammy.

Memory

Memory is stored on a tape of addresses which can be 0 or 1.

The command

x:y is explained in this pseudocode.

if address x is 0:
 jump to line y
 move the pointer left if the current cell isn't the first cell
otherwise:
 move the pointer right and flip the current bit

Special lines

0 is output. It will always be jumped to, no matter what x actually is. It adds the value of x to a bit stream. When the bit stream is 8 bits long, it gets converted to ASCII and outputted.

-1 is input. It will ask for input and store it in x.

-2 restarts the program.

-3 flips the bit.

Anything below terminates the program no matter what.

Jumping to the current line is a NOP.
