The second category of errors is LBA-PC execution errors.  These error messages are normally 
displayed in a message box on the screen.  The LBA-PC reroutes these error messages to the error 
message queue when the queue is enabled. 
Example of a category 2 error: 
Host sends 
 
:PAN 
 X=0; 
 Y=0(^END)

The third category of errors are either fatal or result from some local user action.  These errors cannot 
occur because of remote commands.  This third category of errors is always displayed in a message box 
on the screen and requires user action before continuing.  See the ERR specification for the specific 
errors included in each error category.
