surface
of
the Template the Cursor will
disappear. It will
reappear when
you
bring
the point back
to
within
2"
of
the Template. The
Cursor
will
also disappear if you
press
the
pen
point
against the
Template.
Operating the
Demonstration Program is
easy. You
tell
the program what
you
want to do
—
by
touching one of
the
commands across the
top
of
the
Template, then
where
you
want to
do
it
by
touching
the
Pen Point
one
or more
times on the Display Area.
The
boxes along
the
top
of
the
page
are commands.
They
represent the things
you
can
do with
the
Demonstration
Program. Try
each one out
as
we
explain
it.
COPY
Copy to another
Screen Location
Press your Pen Point into
this box and a rectangle will
appear
on
the
Screen
at
the
Cursor position. You can
move the rectangle
around the Screen
by
moving
the Pen.
If
you
move
further than a
2"
or
so
up from
the surface,
the rectangle will
disappear.
It
will
reappear when
you
move the Pen closer to the
Surface. When you
press the
point down, whatever
is in the rectangle
at that
moment
will
be stored
in the
Color
Computer's
memory.
COPY
uses the
Extended
BASIC
commands GET and
PUT to
move graphics
from place
to
place
on
the
Screen.
When
you
relocate
the rectangle
to
another
place on the
Screen,
a copy
of
the original
contents of the rectangle
will
appear at the
new
location.
The COPY routine must
be
deleted
if
the program is
to
run on
a 16K
Color
Computer.
TEXT
Write
on
the
Screen
Press
your
Pen
Point
into the
TEXT
box, then select
a
point on the Display
Area and press
the
Pen down again.
Now any keys
you type
on
the
Keyboard
will appear
on
the Screen
starting
at
the point
you
selected.
You may
type
text until
you reach the right
edge of
the Screen.
After
that, all
the characters
you
type
will
stack
up on top
of each
other in the
last box.
The
letters displayed
on
the Screen are
not the same
letters normally
displayed
in program listings, program
output etc. They
are actually
'graphic"
characters created
using the
Extended
Color BASIC
DRAW command.
TEXT
uses
the
Color
Computer command PRINT
@
to
position the text,
and
is
very handy for printing
labels
for
your
displays.
DRAW
Draw
Freehand
Press
your Pen Point
into
this box
to draw. When
you
draw
a
line on the
Pad,
the line will appear
on
the
Screen
just
as
though
you were
drawing with
a
Pen. This
command
uses the Color
Computer DRAW
command.
PAINT
Color in
a Closed
Area
To
Paint
a
closed-in
portion
of
the
Screen:
1.
Press the
Pen down
inside the PAINT
box.
2.
Press
the Pen down
inside one
of the 9
COLOR
boxes
along
the
bottom of
the Template.
3.
Press the Pen
down
inside
a
closed
shape on
the
Screen. The
area
you select will
be painted the color
you selected.
A "closed area"
is
one
completely
enclosed
by
lines. If
the
area
you select
isn't completely
enclosed,
paint
will
"leak
out"
and may
paint
the
entire
Screen! If this happens,
just
"stop
up" the hole and paint the
area again.
Of
course,
you
may paint the
background
also, or the
whole Display
Area.
