Commodore MPS 1200 - Chapter 9 Odds and Ends; LOCAL CHARACTER SET SELECTION (Commodore mode only)

Chapter 9
Odds and Ends
In this chapter we'll cover some special features and techniques that
are useful with both text and graphics but don't fit into any particu-
lar category.
LOCAL CHARACTER SET
SELECTION (Commodore mode only)
Lower/Uppercase Character Set
BASIC chr$(17)
Hex 11
Uppercase/Graphics Character Set
BASIC chr$(145)
Hex 91
Secondary addresses 0 and 7 set character sets globally, 0 selecting
the Uppercase/Graphics character set and 7 the Upper/Lowercase
set. You can set a character set locally in Commodore mode,
with chr$(17) to use the low~r and uppercase characters when the
secondary address of 0 has been sent to the printer, or switch to
uppercase letters and graphics by sending chr$(145) even though a
secondary address of 7 was sent to the printer.
These commands allow the printer to mix both character sets on a
single line (although it won't appear that way on your monitor
screen. chr$(17) stays in effect until a carriage return or chr$(145) is
detected. chr$(145) functions until a carriage return or chr$(17) is
detected.
This program shows how each local mode can be used.
