I learned what I know from editing other peoples programs and looking at online ptc blogs. You can edit programs by going to "Write Program" and typing Load"(program name)". And a good blog is http://www.petitcomputerbasic.blogspot.com/

It takes a while to learn, but when and if you do it'll be worth it.
