The PEN used when the computer is first switched on, is number 1. Look at Table 2 and you will see
in the mode 1 column, that PEN number 1 is colour number 24. If you now refer to Table 1, you will
see that colour number 24 is bright yellow, which is the colour of the characters (PEN) when the
computer is first switched on.
We have just changed the PEN to number 3. Looking at Table 2, you will see that PEN number 3 is
colour number 6 in mode 1. Now refer to Table 1, and you will see that colour 6 is bright red.
At the moment, we are using PAPER number 2 and PEN number 3. We can now go on to change the
colour of these. We do this by using the INK command.
The INK command has two numbers, the first is the number of the PEN or PAPER to be changed,
the second is the colour that the PEN or PAPER is to be changed to. Look at Table 1 for the colour
numbers. As an example, we will show how to change the colour of PAPER 2 to black and the colour
of PEN 3 to bright white.
In Table 1, you will see that the colour number for black is 0, and the colour number for bright white
is 26.
Now type in:
ink 2,0 [ENTER]
(As explained, 2 is the current PAPER number, and 0 is black.)
Now type in:
i n k 3 , 2 6 [ENTER]
(3 is the current PEN number and 26 is bright white)
Now fully reset the computer by pressing [CTRL] [SHIFT] and [ESC] keys.
As explained earlier, when the machine is first switched on, or reset using [CTRL] [SHIFT] [ESC],
the PAPER number is 0 and the PEN number is 1. The colour of the PAPER is 1 (blue) and the
colour of the PEN is 24, (bright yellow). These would be typed in as ink 0,l for the PAPER, and ink 1,
24 for the PEN. To change these immediately to white characters (PEN 1 on a black background
(PAPER),type in:
ink 0,0 [ENTER]
Then type in:
i n k 1 , 2 6 [ENTER]
