2.1.7 How to use graphic characters
You can define a character (symbol) yourself by using the FONT$ function.
You can define character codes between 128 and 159, and between 224 and
255.
The FONT$ function is used as follows:
FONT$
(<expression>) ="<variable
1
>, <variable
2
>, ....
<variable
8
>"
The <expression> specifies the character code to be defined.
To define the character code 128, type,
FONT$(128)
="<variable
1
>,
... , <variable
8 RETURN
As the <variable 1 >to <variable 8 > (<data 1 >to <data 8 >) can usually
be constants, they are decided with a diagram.
