MMBasic Style Guide for GPT

Lennart · June 26, 2025, 9:24pm

Hey,
ChatGPT knows Basic but gets the details of MMBasic often wrong. As I would like to use it a bit to brainstorm I used my bits of code and the official guide to create an (opinionated) style guide for MMbasic.
You can find the result here:

# MMBasic 6.0.0.2 Style Guide for PicoCalc

**Description**: This guide captures recommended coding conventions and formatting practices for writing clean, consistent, and visually expressive MMBasic code for the PicoCalc. 

**Goal**: Use it to generate, review or format MMBASIC code.

**Reference**: https://geoffg.net/Downloads/picomite/PicoMite_User_Manual.pdf

## Beginning

- Start each file with a descriptive title / short description, followed by date and version

```  MMBASIC
' Matrix Effect
' 06/25, v0.1
```

## Configuration

- Always declare basic settings up front.

Maybe you might find it useful.
I am Interested in your comments / feedback.

GPT wrote me a snake program (as a test) with a single prompt - I only had to fix the ascii keys. So now it kind of knows MMBasic.

Hi!

I add a “trick” word for avoid standard Basic languajes mix confussion in GPT…

Try adding “webmite” , “picomite”…

Like:
Make a snake game in mmbasic picomite.

Good luck!

yes, I tried that, too.
but the results were inconsistent for me.
that’s why I thought to let it create a style guide for for it…
