Thanks for writing some commented SAMPLE CODE for us Squeak newbies. Very NEEDED and appreciated!
I've been at this for about two weeks, and it's a little tough to make the transition between making a car go in circles to writing something useful.
I know enough to open a Morphic project, get your file list, and open it with the zip viewer. This is as close to the "file in" as I can seem to get, as the "load file" command will not show your file. I can load your code from there, but now what do I do with the blank screen? I'm obviously not loading or running it properly.
