28 When the computer finds any program on the cassette it will show the name of the program on the screen. When it finds the program it is looking for it will print Loading to let you know that it is now loading the right program. When the computer has finished loading the program it will print the > prompt. It will also automatically stop the tape if you have automatic motor control, if not then you will have to stop the tape manually. The program is now in the computer. You can type RUN RETURN to make it work, as usual. There is one more useful feature to do with loading and saving programs.
Instead of typing LOAD "MYPROG" RETURN you can type CHAIN "MYPROG" RETURN This not only loads in the program MYPROG but also starts it working as soon as it has loaded. It is normally more convenient to use CHAIN than LOAD . Cataloguing a tape If you forget what programs you have on the tape then you can get a catalogue by typing *CAT and then playing the tape, but you’ll have to wait until the tape has run through the programs. What the numbers mean A typical catalogue looks like this WELCOME 00 0084 INTRO 08 088E INDEX 0A 0ABA KEYBOARD 25 2545
