Title: Encoding eight characters as a single number
Post by: Deep Toaster on October 31, 2011, 07:30:51 pm
Just wanted to share a little routine I made to store eight bytes of uppercase text as a single real variable (for example for high-score player names).

This would be awesome for lists, because people are less likely to delete lists than Real Variables

and you can create lists, but you can't create strings!
it all works out!!! ;D

Yep, that's what I'm doing. A list of just ten elements (ninety bytes) is enough for five names and five high scores :D

Have you tried storing strings directly into lists?

Why do that when you can store the same string in one-eighth the memory? :D
