Input-Output Section
IBM 3270 terminal. If this clause is omitted for terminals in conversational mode,
no error enhancement occurs. For error enhancement, BELL must be specified.
IN FIRST
enhances the first field that is found to be in error. For terminals operating in
conversational mode, IN FIRST is the only recognized enhancement option.
IN ALL
enhances all fields that are found to be in error. If IN ALL is not specified, only the
first field containing an error is enhanced.
WITH [ NO ] AUDIBLE ALARM
enables or disables the audible indicator when an error is detected.
The ERROR-ENHANCEMENT option allows you to control some aspects of the error
processing. For example, when an ACCEPT statement executes, the TCP checks the
contents of input fields against the requirements of a PICTURE clause and any
constraints, such as those imposed by a MUST BE field-characteristic clause. ACCEPT
processing attempts to indicate which field is in error.
