ATARI Light Pen Operator's Manual
16K Version of PALLET
Figure 4 is a television screen display for this program. A flow chart
for the program is shown in Figure
and Figure 6 is the complete
program listing.
If you have already tried the 8K version of this program* you will be
able to see the additional features which this version provides*
primarily because this version assumes there is more memory available
to work with. The 8K program had only five menu choices along the
right side of the screen. This version has 12 menu choices on the
right side. Any of these choices may be selected by pressing the pen
to the screen in that area.
Of the 12 choices* the top five are known as drawing modes* the next
four are color modes and the last three are functions to be performed.
Within the blocks which define the drawing modes is a segment which
acts as an indicator bar. This indicator bar is the same color as the
border and appears at the far left edge of the selector box
representing the current drawing mode. There is another indicator bar
which appears in one of the color selector blocks. This tells you the
current color of the pen.
Among the color modes* you can select to draw in red* green* blue or
"erase" color (which sets the spot under the pen tip to the background
color). These selection modes are identical to those used in the 8K
program* however the selector blocks are larger and more clearly
defined.
In the 8K version* you only had the ability to draw in the ELASTIC
mode. Elastic refers to a line which acts like a rubber band as the
pen moves. This program provides the selection of ELASTIC mode by a
large E selector box.
