The INDEX file identifies the cassette, and includes test sequences for setting the correct playback volume on the recorder. It should be star-loaded by typing:LOAD “INDEX”
The file will then be loaded directly to the screen, and should appear as shown above. The remainder of the file should appear as a sequence of lines showing the character-set:

The remaining files on the cassette should be loaded and run normally; e.g.:LOAD “ADDUP”
