Grid-Line Screen-Format Displaying Mechanism

This section describes the control for the grid-line displaying function and how to specify the grid line and the character data.

There are three ways to control the grid-line screen format:
  • Grid-line draw control
  • Deletion control in the grid-line information buffer
  • A combination of grid-line screen format and a user-defined screen format
Note: The control codes should be defined to be set in a different field from the character data. If these control codes are set in the same field as the character data, the grid line will not be displayed correctly or unexpected data will be displayed.

Hexadecimal numbers are used for the control codes and the data in the following description, unless otherwise specified.
