�¡Explanation

The REGISTER-VARYING-INDICATOR method registers a data item that handles data in the variable-length format and a data item that handles a NULL value. When a field that is fetched contains a NULL value, an indicator variable of -1 is set. When a NULL value is set in a field, an indicator variable of -1 is set.

�¡Note

GET-DATA-LEN and GET-DATA-DAT must be elementary items associated with the same group item.
