# Play with Docker and Assembly programming language > Learn how to combine modern Docker technology with the classic x86 Assembly programming language. This guide provides a step-by-step "Hello, World!" example for both MS-DOS and Linux environments. ---  **TL;DR** This article revives 1990s x86 Assembly nostalgia by assembling and running a "Hello, World!" `.asm` file with zero local install, using the `esolang/x86asm-nasm` Docker image from both a DOS/PowerShell console (`%CD%`) and Linux (`${PWD}`). When I was younger than today, during my studies, I was playing with the x86 Assembly language on my `386DX40` computer; this was in the years 1993-1995. The beginning of Windows 3.1 that I did not like. *If someone had asked me if graphical interfaces would be successful, I would have said no, of course not.* I remember that I wrote a resident program (TSR which stands for **T**erminate and **S**tay **R**esident) which, once loaded into memory, monitored the keyboard and recorded the keys that had been pressed in a file on the hard disk. Yes, it was a password stealer. Just for fun and, above all, for the challenge of it. And now, in 2023, I was wondering if it was still possible to run `.asm` files on my computer. It was an excellent reason for this article. *The same nostalgia trip, one language later: [Play with Docker and Pascal](/blog/docker-pascal), where I compile Turbo Pascal sources I published thirty years ago.* By searching on [Docker Hub](https://hub.docker.com/), I have found this image: ## Let's play in MS-DOS Let's test our Docker image in DOS this time. Please start a **DOS** console and run `mkdir C:\tmp\assembly && cd C:\tmp\assembly` to create a folder called `assembly` in your DOS environment and enter it. Please create a new file called `Hello.asm` with this content: **Hello.asm** ```asm ; Our data section (i.e. our variables) SECTION .data ; Our null terminated string hello: db 'Hello, World! This message comes from Docker.', 0 ; Our entry point SECTION .text global _start _start: mov edx, 45 ; 45 is the length of our "hello" message mov ecx, hello ; The name of our variable is "hello" mov ebx, 1 ; We'll write to stdout mov eax, 4 ; System call number (sys_write) int 0x80 ; Triggers software interrupt 80 mov ebx, 0 ; Next three lines are equivalent to exit 0 mov eax, 1 int 0x80 ``` To run the script, just call Docker, like this: ```bash $ docker run --rm -v %CD%:/code -w /code esolang/x86asm-nasm x86asm-nasm hello.asm Hello, World! This message comes from Docker. ``` > **Of course you can play under Linux:** > > Just replace `%CD%` by `${PWD}` and the instruction will be recognized by Linux: `docker run --rm -v ${PWD}:/code -w /code esolang/x86asm-nasm x86asm-nasm hello.asm` Same idea, different language: I've also played with [Pascal](/blog/docker-pascal), [Python](/blog/docker-python), and [Java](/blog/docker-java) using this same "zero local install" Docker approach.
