EXAMPLE #2:
A 3X3 character matrix of characters on a black background is to be displayed on the screen, using 2-color character codes.
2 skipped lines are required below the first line of characters, 3 skipped lines are required below the second line of characters,
and 4 skipped lines are required below the third line of characters. The first line of characters will use color attribute 0, the second
line will use color attribute 1, the third line will use color attribute 0 for the first character, color attribute 1 for the second character,
and color attribute 2 for the third character. This is shown in
Figure 42.
