Hi Nicolas It becomes quite the memory hoarder as the document goes on (as you can imagine) but I created one that is basically an indexed svc-like array. It can be char or word based.
I also created (although it wouldn’t suit your purpose) a very complex undo/redo for a number of prototype game show apps that covered anything that happened. It twists your brain working out the infinite possibilities but is doable. It often just takes a bit of research and planning - especially if you are breaking new ground. I’ll post up a simplified script in a bit.
