SASM Lang

Simple Assembly is a simple high-level assembly-like interpreted scripting language. It's designed for educational purposes.

Basics

SASM uses "instructions" to perform operations. Each instruction is a single line of code. It does not support functions or procedures. It also doesn't support any kind of modules or libraries. You cannot import any external code.

SASM implements the following data types:

• Numbers
• Strings
• Floats

Variables are partially statically typed. Their type is determined by the first value assigned to them. Once a variable is assigned a value, it's type cannot be changed.

Download and try

You can download the latest prebuilt binaries from the releases page. There's no need to install anything, since all the binaries are statically linked.

Also check out some example programs in examples.

Syntax

A single instruction is made up of 2 parts:

1. The operation
2. The arguments

Example:

VAR x

Here, VAR is the operation and x is the argument.

2nd Example:

MOV x,13

Here, MOV is the operation and x,13 are the arguments. Arguments are separated by commas, with no spaces.

Loops

Since SASM does not allow defining code blocks, loops are implemented using CMP and JNE/JEQ instructions. Here's an example of a simple loop that prints the numbers 1 to 10:

VAR x
MOV x,1

CMP x,11
JEQ 4
DMP x
INC x
JMP -4
