The $FSTERR function returns a variable length string of up to 79 characters that contains the prefix and the first counting error message or request cancellation message you received since the last time that the count was reset to zero. $FSTERR returns a null value, if Model 204 has not received a counting error or request cancellation message since:
- The beginning of your Model 204 session
- The last call to the $ERRCLR function
- Processing a User Language OPEN statement
For more information about counting errors or request cancellation messages, refer to the Rocket Model 204 Messages Manual.
