Using the Graphics Character Set
The following example creates an OSD screen which illus-
trates several features of the MC144144 including the use of
the graphics character set to generate a large font word. The
particular features shown are purely for demonstration pur-
poses and not intended to suggest a particular application.
For the sake of brevity, the “text” to be displayed will be
shown as a string within quotes rather than as the actual
command sequences required. Single quotes, ’, will signify
standard characters while double quotes, ”, will signify
double wide characters.
