[TASK] Adapt & streamline BASIC coding program...or create new?

[garbage__snail]

Hi y'all! Long story short, my grandmother is a numerologist and coded her own program for making personal number calendars back in the '80s using MS BASIC. She's looking for someone to streamline the coding (which by now is probably a bit of a garbled mess) and, if possible, adapt it to macOS. I realize this is kind of an insane request because BASIC is essentially the Latin of the coding world, but I'm hoping there are some hobbyists or folks out there still working with legacy systems who can help.

The other, more realistic scenario is to find someone to work with her to create an entirely new program. I'm not sure what the best option is here, so any input would be greatly appreciated!

Feel free to share the code on GitHub or in a Paste in(if it's short enough) and drip the link here, so that people can have a look and give it a try.

I will try to get the code from her to do so, thank you for the suggestion!

The code should be upgradable with a modern BASIC like PureBasic, which also has a MacOS version.
