CP/M Error Messages
Messages come from several different sources. CP/M displays error messages when there are
errors in calls to the Basic Disk Operating System (BDOS). CP/M also displays messages when
there are errors in command lines. Each utility supplied with CP/M has its own set of messages.
The following lists CP/M messages and utility messages. One might see messages other than
those listed here if one is running an application program. Check the application program's
documentation for explanations of those messages.
