In those days we had no internet. There were no books about LOGO programming in the library. The math teacher taught us the basic commands, but didn't explain the REPEAT command so we could understand and the importance of it. So I had no examples to follow or a real mentor to suggest a book. Later I learned some basic Pascal, but it was only in high school when I taught myself programming in C++.
