Scratch

If you don't reset the variables to 0 or clear the lists at the start of every run of the program, all the data will remain saved along with your project

So for an app like my Pacman that uses a big (1008) item list, I could simply write the list, save the app without erasing it, then delete the script block that writes the list and now all that data is permanently stored in my Pacman project file?

Yep - that would work! Unless the list got erased at the end of the script, of course 

Yep, the only way it ever disappears is if you don't save it or if you use a script to delete it.
You can just click the (+) next to where it says the length of the script to add a new item, then click on it to write and change it, without a script.

Very interesting. I had considered doing some testing cause there are practically endless variations on "is it faster to do it this way or that way" but that is definitely a major tip on the looping. In my case, the map data really only has to be programmed once. Knowing what I know now, it is and will forever more be prefigured and saved into the project so yay that massive program script is deleted and my project is already getting easier to edit, but I'll save that for the right post 
Thanks again, I'm learning all kinds of stuff today!
