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
The program gives 32 registers, each having their ascii character ids from 32-64 (<space>-@)
| Syntax | Description | Example |
|---|---|---|
I<reg> |
Increments register | I# |
D<reg> |
Decrements register | D# |
L<reg> |
Adds the instruction pointer value to the register | L! |
J<reg> |
Jumps to the pointer stored in the register | J! |
Z<reg1><reg2> |
Jumps to the pointer in the register2 if register1 is 0 | Z*% |
E<reg> |
Ends execution if register is 0 | E* |
K |
Ends Execution | K |
P<reg> |
Prints the register value as an ASCII char | P! |
This simple Pico200 program prints the alphabet from A-Z

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
