Up to two sets of grid-line screen-format data can be stored within the
PC400.
To store the data of the grid-line screen format, PC400 provides the grid-line
information buffers F and B. When PC400 receives data which contains the identification
F or B from a host system, PC400 displays the data of the grid-line screen
format and the character data concurrently. The following figure shows the
relation between the designated grid-line information buffer and the character
data to be displayed.
