Using Textset
TEXTSET features an OSD mode that paints on the screen
in a manner similar to a Text Mode display. The memory
is organized using the current information in the Text Po-
sition register, and the display follows the current setting
The line, Select: ENTER EXIT: MENU, appears in row 12,
starting in character column 2. These are displayed as single-
wide characters.

in the Display register. The default display parameters for
the OSD are 15 lines per row, Drop-Shadow mode. The
TEXTSET command can be followed by successive
WRITE CHAR commands interspersed with the RETURN
command at the appropriate points to paint on an OSD dis-
play starting at the top of the Text window. These com-
mands are set by the Text Position register, moving to the
next line at each RETURN command. The display scrolls
if a RETURN command is sent when at the bottom of the
Text window. A subsequent TEXTSET command clears the
screen, thereby generating a new OSD screen.
The following example shows an OSD display generated
using TEXTSET. This screen is a paint-on rather than pop-
on. Features like flash are included in the command se-
quence for demonstration purposes.
The Text display is first set to 4 rows at the bottom of the
screen.
The next two commands are used for positioning and color.
