# Pico200

This is an esoteric programming language designed to be very small.


This repository contains a **204-byte interpreter** for the language written in the boot sector.


The user-written source code is in a different sector (of the `disk.img`), which the program reads and executes

## Instructions

The program gives 32 registers, each having their ascii character ids from `32`-`64` (``-`@`)

| Syntax        | Description                                             | Example |

|---------------|---------------------------------------------------------|---------|

| `I`        | Increments register                                     | I#      |

| `D`        | Decrements register                                     | D#      |

| `L`        | Adds the instruction pointer value to the register      | L!      |

| `J`        | Jumps to the pointer stored in the register             | J!      |

| `Z` | Jumps to the pointer in the register2 if register1 is 0 | Z*%     |

| `E`        | Ends execution if register is 0                         | E*      |

| `K`             | Ends Execution                                          | K       |

| `P`        | Prints the register value as an ASCII char              | P!      |

## Simple Example

This simple Pico200 program prints the alphabet from `A`-`Z`

```p200

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!I!I!I!I!I!

I!I!I!I!I!

I*I*I*I*I*I*I*I*I*I*

I*I*I*I*I*I*I*I*I*I*

I*I*I*I*I*

I%I%I%I%I%I%I%I%I%I%I%I%I%I%

L%

L#

P!

I!

Z*%

D*

J#

K

```

## Run

To compile and run Pico200, you need to have **NASM** (for compiling) and **QEMU** (for running the image from a VM)


This repo also contains a simple `compile.sh` file that compiles the assembly to binary, combines the binary and the source code `program.p200` to a single `disk.img` file and runs with QEMU.



*Tested with Ubuntu 24.04.1 LTS, NASM version 2.16.01, QEMU emulator version 8.2.2*
