The $ERRMSG function returns a variable length string of up to 79 characters containing the prefix and text of the last counting error message or request cancellation message received by the user.
A null value is returned if no counting error or request cancellation message has been received since:
- The beginning of the user's Model 204 session
- The last call to the $ERRCLR function.
- Processing a User Language OPEN statement
Refer to the Rocket Model 204 Messages Manual for more information on counting messages. This function takes no arguments.
