INSTRUCTOR NOTES 14SAVING TO TAPEWe explain how to use the cassette recorder to save programs.This lesson can be used any time after Lesson 3. We put it this late in the bookbecause most programs up to this point are relatively short and uninteresting, notworth saving. However, use your own judgement and insert this lesson at an earlierpoint in the flow of lessons if you wish.The Commodore tape recorder is similar to ordinary recorders which play music, butthe computer can automatically turn it on and off.Ordinary audio tape cassettes can be used. However, the tape must be able to recordperfectly. Even one tiny bad spot (such as a fold in the tape) will "drop a bit" and therecorded program will be wrong.Short tapes are best. Programs use from 20 seconds to five minutes worth of tape. Youwill put one long program or several short ones on one tape. You do not want to fill a30 minute tape with programs, because it would take a long time to get to the lastprogram, even using fast forward/On some versions of the Commodore 64, you have to press the CTRL key to continueLOADing and VERIFYing operations.QUESTIONS:1. What is a "file"?2. How long can a file name be?3. How do you check that the program got onto the tape OK?4. What happens to the program already in memory if you LOAD another program?5. Does the file name have to be the same as the program name?6. Write a short program, SAVE it, VERIFY it, do NEW and then LOAD it.7. If a program is put into a file, is it still in memory?79
