If this message appears on the screen while operating, your disk is full. Morse Academy can not create tests, write new log information, or save keyboard files. This can occur during initialization if your system only has 360KB diskettes. You must remove unneeded files from your Morse Academy disk to be able to continue using the program. The Morse Academy discette contains the file MANUAL.PRT, which is about a 40 page manual describing the operation of the program. If you have another copy of this file, or have already printed it out, it may be deleted to save around 135K bytes of storage. This can be deleted by typing the DOS command: DEL A:MANUAL.PRT You can also delete old log files by typing the DOS command DEL A:LOG-?.VW (perhaps you will want to save the history first by copying it to another discette, e.g. COPY A:LOG-?.VW B:). If you feel the history is not really needed in the future, use the Morse Academy VIEW command options to turn off all logging, or set the logging mode to keep only the history of the last session.
