<p>0 A data entry screen for an interactive data entry system provides a means for identifying to a user those fields where data may be entered and those fields in which data must be entered. Initially, the formatted data entry screen is displayed to the user with mandatory data entry fields highlighted and optional data entry fields without highlighting. As data is correctly entered into either a mandatory or optional data entry field, the data is processed and redisplayed without highlighting. The interactive data entry system checks the correctness of data entered by the user in the mandatory and some of the optional data entry fields, and if an error is detected, the incorrectly entered data is redisplayed in a mandatory or an optional data entry field.</p> |
