SeMo-PATH, is derivation of PATH, that is a two-dimensional language inspired by Brainfuck and Befunge. Unlike PATH's environment, SeMo-PATH's consists of a 2D plane of memory cells all initialized to zero, on which is also written the program itself, and character-based standard input and output. PATH understands the following commands:
Command | Explanation |
---|---|
$ |
Start the program here, heading right. |
# |
End the program. |
+ |
Increment the current memory cell. |
- |
Decrement the current memory cell. |
} |
Move to the memory cell rightwards. |
{ |
Move to the memory cell leftwards. |
V |
Move to the memory cell downwards. |
A |
Move to the memory cell upwards. |
, |
Input an ASCII character from standard input into the current memory cell. |
. |
Output an ASCII character from the current memory cell into standard output. |
/ |
If heading in direction:
|
\ |
If heading in direction:
|
^ |
If the value of the current memory cell is not 0, turn up. |
< |
If the value of the current memory cell is not 0, turn left. |
> |
If the value of the current memory cell is not 0, turn right. |
v |
If the value of the current memory cell is not 0, turn down. |
! |

As in Brainfuck, any character not understood as a command is simply skipped over.
Computational Class
As any PATH program is also a SeMo-PATH program, and PATH is Turing complete, so SeMo-PATH is Turing also complete.
