Commenting isn't just for other's to read your code, it's also for yourself. I find commenting my code helps me gain a greater understanding of what I just wrote.
Many times I've gone back to old projects, just to stop and think to myself, "what the heck was I doing." Now it's your choice if you want to comment or not but remember this: It helps you just as much as it helps others.
Is that so? I would love to see your reasoning behind that, because my tests say otherwise.
Remember, what you are saying is true for Petit Computer but I have yet to see anything about comments slowing down programs for SmileBasic.
Actually if you hold start then run a program, the button command will actually read it. The code for start is 8192.
The only use I can think of is starting a program in some sort of debug mode.
