When indicates the second display pattern, the process moves to step 8 to fill in the corresponding line by referring to the value obtained by subtracting the above variable H1 from the number of display lines, and in the next step 9, all Determine whether or not the line has been filled. When all the lines have been filled with the first display pattern, the process moves to step 11, where the variable H1 is changed to the third display pattern, and then the process moves to step 6, where a variable indicating the display line is changed. Clear H+, move on to other processing, and wait for the next display processing timing.

Furthermore, if the determination result in step 2 is not the second display pattern, the process moves to step 11,
In step 11, the step 11 refers to the variable H2 and determines whether or not it is the third display pattern for displaying a character mode in the graphic display area (IIOA). Whenever the variable Ht indicates the third display pattern, character display data from the font table is drawn on the line where the dots are drawn, and in the next step 13, it is determined whether or not the characters have been drawn on the entire surface. When the determination is made and the character display according to the third display pattern is finished, the process moves to step 14, where the variable H indicating the display line and the variable H indicating the display pattern are cleared, and other processing is started. Wait for the next display processing timing.

Also, step 4 above. Step 9 or Step 1
If the determination result in step 3 is No, that is, the display according to the first display pattern, second display pattern, or third display pattern is not completed, in any case, the process moves to step 16 and the display line is shown. After incrementing the variable H1 and reserving the next rendering processing time, the process moves on to other processing and waits for the next display processing timing.

Note that by changing the next rendering processing time, the state of change of the screen according to each of the display patterns can be arbitrarily varied.
