To explain this further, we can associate the PEN and PAPER on the monitor screen to an actual
PEN and piece of notepaper. As the colour of the INK in a PEN can be changed, so the colour of the
characters on the screen can be changed. As the colour of notepaper can be changed, so the colour of
the PAPER on the screen can also be changed.
To change the colour of the BORDER type in:
border 0 [ENTER]
You will see the BORDER colour change from blue to black. If you refer to Table 1, you will see that
0 is black. The BORDER can be changed to any of these colours by typing in: border then the colour
number required.
Now type in:
cls [ENTER]
to clear the screen.
To see the PAPER colour change, type in:
paper 2 [ENTER]
You will see the background colour behind the word Ready change to bright cyan. Now type in:
Cls [ENTER]
to clear the screen again to the new PAPER colour.
To see the PEN colour change, type in:
PEN 3 [ENTER]
You will see that the PEN colour has changed and the word Ready is printed in bright red.
Now type in:
cls [ENTER]
You will find it easier to understand what has happened here if you refer also to Table 2. When the
computer is first switched on, the PAPER used is number 0. If you look at Table 2, in the first
column, you will see PAPER number 0. If you now look along the same line in the Mode 1 column,
you will see colour number 1.
If you now refer to the master colour chart (Table l), you will see that number 1 is equal to blue,
which is the colour of the PAPER when the computer is first switched on.
We have just changed the PAPER to PAPER number 2. Refer to PAPER number 2 in the left column
of Table 2, and you will see in the mode 1 column that this is colour number 20. Now look at Table 1
and you will see that colour 20 is bright cyan.
