Mang is an esoteric language created by wolfmitchell for no reason at all. The language uses Lua to parse it, as data is stored as Lua tables. The instructions are numbers in tables, and the tables instructions are stored in are nested.
Instruction set
Copy-pasted directly from the interpreter's source:
00 - next cell, basically a blank space. 01 - previous cell 02 - add to cell 03 - subtract from cell 04 - increment program counter 05 - decrement program counter 06 - if cell = 0 then go up 07 - if cell = 0 then go down 08 - if cell = 0 then go left 09 - if cell = 0 then go right 10 - exit program 11 - print value in current cell 12 - do nothing 13 - debugger 14 - if cell != 0 then go up 15 - if cell != 0 then go down 16 - if cell != 0 then go left 17 - if cell != 0 then go right 18 - if cell = 0 then go to beginning of next line 19 - if cell != 0 then go to beginning of next line 20 - if cell = 0 then go to beginning of next line at col 2 21 - if cell != 0 then go to beginning of next line at col 2

Explanation
This is generated, so it follows a static format.
The chunks of 02s set the value of the current cell to the ASCII
value of the desired character. 11 prints the character.
The 18,20,17,03,16,09,18 code at the end of every line sets the value of the current cell to 0, then jumps to the next line.
How it does it:
18- Just in case the cell is already 0, jump to the next line immediately.20- This is where it is because when the program counter exits the loop going right-to-left, it will hit this, making it go to the next line. It has to start at column 2 so when it goes right again, it hits09making it go left.17- If the cell still has a value other than 0, go right.03- Subtract 1 from the cell.16- If the cell has a value other than 0, go left.09- Make sure we are going left, just in case.18- Jump to next line.
