Quote from: hutch-- on September 07, 2022, 09:50:24 AMWhile putting strings into a text file makes sense, rather than have to convert numbers both ways, having a structure of your own design with as many numbers as you wish to preserve as structure members is fast to load, save and internally process. This is why I use a binary file for numbers that must be preserved.
