Radio Shack TRS-80 X-PAD GT-116 - 9; Brushing on the First Coat

9/ Brushing
on
the
First
Coat
A
paint
program
Jets
you paint a
certain figure
you
have
just
drawn
on
the
X-Pad.
Before
using
the
X-Pad's
PAINT
routine,
read Chapter 6 of
Going Ahead
With
Extended
Color BASIC carefully!
For
instance,
when
you
specify
two
diagonal
points
with
the
Pen, the
following
program draws a box
and
then
paints
the
box
when
you move
and
press
down
the Pen in
a
part
of
the
margin which
has
been
defined
as a
"color-coded
menu",
(Actually,
we're
jumping
a
little
ahead of ourselves
but
bear
with
us
—
you'll
like
what's
about
to follow!)
Whenever you
want
to
clear
the
Screen,
just
move
the
Pen
to the bottom margin.
With
this
program,
you
can
color-code
three
of the
four
margins
on the X-Pad. The
colors
available
depend
on
the
color
set
currently
in use:
If the Color
Set
is
0,
then
, .
.
if
the Color
Set
is
1
, then
. .
.
green/yellow/blue/red
(green
is
the
background
color
and you
can
set the
three
margins to
the
other
three
colors)
buff/cyan/magenta/orange
(buff is the
background
color)
You can
then
define each
margin
with
a color.
For
example:
left
=
3
(blue)
right
=
2
(yellow)
top
=
4 (red)
bottom
=
