Six instruction language :)

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

this is my first one btw
Six instruction language is a language that has 6 instructions. An input stream is absent. It has 3 registers and each are stored as a number from 0 to 15. Register 3 is the output of the program.

Instructions

The following instructions are available. Please heed that the first register is named r1, the second r2, and the third r3.

Six instruction language :)'s instructions:

Instruction	What it does
1	Set r1 to n
2	Set r2 to n
3	Set r3 to r1+r2
4	Wipe r3
5	Wipe r1 and r2
6	Invert r1 (set r1 to 15-r)

To pass an argument to the commands 1 and 2, you proceed the command with the following encoder table:

encoding

argument	input
0	a
1	b
2	c
3	q
4	w
5	e
6	d
7	f
8	g
9	r
10	t
11	y
12	h
13	i
14	j
15	u

So 1e means to set r1 to 5.

Example Programs:

Addition

1+1:

1b2b3

Output:

2

because 1+1=2

State Inversion

This program sets the value of the first register to five, inverts, and prints it:

1e63

Interpreter

• Common Lisp implementation of the Six instruction language :) programming language.
