Description
The ON READERROR command executes the specific <command> when a data entry error is made. Data entry errors are: invalid dates, number out of range, failed VALID condition. ON READERROR can be used to replace the default error messages that are given when these errors occur. If no <command> is specified with the ON READERROR command, any previously issued ON READERROR setting is cancelled.
