Error
messages 
FileStore can produce two main types of error message, corresponding to the
two types of error condition: 'fatal' errors and 'non-fatal' errors.
Fatal errors should only happen very rarely. They are not really fatal, just
serious enough to stop FileStore working temporarily. FileStore indicates a
fatal error by flashing its mode indicator about once a second, until you lift
the access flap and put it into maintenance mode. To see the error message,
which you will need to diagnose and cure the problem, use
the *REPORT command.
Non-fatal errors are more common, particularly when users are new to
FileStore and so more likely to make mistakes. They do not stop FileStore
working, but simply result from FileStore being asked to carry out a command
which it cannot perform. FileStore indicates a non-fatal error by displaying a
message on the screen of the user who typed the offending command.
Some of the non-fatal errors are described here as 'program' errors. These
occur when the user is using a program which has asked FileStore to do
something illegal. This is most likely with BASIC programs written by users.
If this is the case, they should check on their program, with help from the
BASIC
User Guide.
If this is not the case, contact the program supplier for
help.
