Bad command
means that you have incorrectly named the program, either by exceeding the number
of permitted characters in a field, or by introducing an unwanted space or punctuation
mark.
Type mismatch
means that you have omitted the quotation marks
Syntax error
means that you mistyped the word run
Drive A: read fail
Retry, Ignore or Cancel?
means that the computer has failed to read data from your disc. Check that you have
inserted the correct disc and press R to Retry. If the above message continues to
appear when you attempt to run that particular disc, it is likely that the disc has been
corrupted, or has not been correctly formatted using Amstrad CP/M.
Finally, if the message:
Press PLAY then any key:
appears on the screen, the disc drive(s) or the interface unit has not been correctly
connected to the computer, or the disc drive is not plugged into the Mains Supply and
switched on.
Note that if you wish to run a disc program after previously operating the Cassette
Datacorder, it will be necessary to issue the |disc command, described in the next
section.
MEMORY USAGE WARNING
The DDI-1 disc interface reduces the amount of memory available in the CPC464 by
1280 bytes. This may result in some cassette-based software failing to operate
correctly if run whilst the disc system is connected to the computer.
The 'Home Runner' demonstration on the CPC464 Welcome cassette is an example
of this aspect of operation.
If you encounter any such problems with cassette-based software, first eject any disc
present in the drive(s), then switch off the computer and disc drive(s).
Unplug the interface unit from the rear of the computer, and then switch on the
computer again. You will now be able to run the cassette in the normal manner.
