ESC = Character Font Image Download
This sequence starts a character font image
download. Use a maximum of 94 characters.
If you load less than 94 , all character codes
must be continuous from the first character
code .
You can select the downloaded font with
ESC I CHR$(4) or ESC I CHR$(6).
The two parts of the ESC = control code are:
1. Part one includes count 1, count 2, and code. Use
this part once for each ESC = command.
2. Part two includes the attribute and col.1 through
col.ll. Repeat this part for each character you
download.
Part
CHR$ (27) ;"="; CHR$(countl) ;
One
CHR$ (co un t2) ;CHR$(20) ; CHR$(cod e );
Part
CHR$ ( attri bute) ;CHR$(0) ;
Two
CHR$ (co l. 1) ; ... CHR$ (col . 11) ;
• Count 1 and count 2 show how many characters to
download. The next section describes how to calculate
the values of count1 and count2.
• Code is the ASCII decimal v al ue for the first
downloaded character. The download characters
replace normal characters starting at that code point.
For example, to download a character set that replaces
characters beginning with the uppercase letter "A",
code = 65 (ASCII "A" = dycimal 65). You can
download to any point from decimal 33 through
decimal 126. All character codes are consecutive from
the starting code point.
