in walls you use a logic of a maze to run instructions


in walls there is places where numbers is stored. the program pointer itself has a stack. then the primary memory is a cell based strip

0: 0 is the path and is followed by the program pointer
1: 1 is the walls. the program pointer can't go into walls
>: move the memory pointer to the right
<: move memory pointer to the left
number: if you put a number on the track then the program pointer will pick it up and store it in the stack for later use on the memory band. to use a 1 or a 0 you type a # in front of it
!: a key. you can name keys using only numbers. keys are used for doors or ~. you put the number the key in front of it
~: a door. you name doors with a number and the corresponding key. after the door has been opened the program pointer can pass through it like a 0. else it behaves like a 1. you put the number of the door in front of the symbol
o: a hole. add the number of the current key to the current memory cell.
"o": a hole but put it in as a ascii character
/: print the current memory cell
"/": ascii variant of /
=: go left if the current memory cell is zero. else this operator behaves like 0
