When your Program gets too Large...

I was working on my programming for my Sensor Overload entry (using the basic NXT-G), when suddenly my program froze up. I attempted to save the file, but it unfortunately didn't work. I had to exit the program and it resulted in me losing a good chunk of programming (I hadn't saved in about 15 minutes). Frustrated, I worried that my program would never work. After all, I wasn't even close to finishing it, and it was already freezing up. I decided to try and find tips on the internet. The first page I went to was extremely helpful. It had many tips, and since then I haven't had such terrible problems. A few of the tips are obvious, but most of them are very helpful. Go here(link) to check it out for yourself. A special thanks to the person(s) who was thoughtful enough to share the tips with us! :-)
