Using SQ-2000 Commands with BASIC
Master Select Codes
Most versions of BASIC use the LPRINT command and the
CHR$(n)
function
to send codes to the printer. In the
CHR$(n)
function the value
n
is the number of
the code that you want to send to the printer. For example, to set a right margin
at column 60, the SQ-2000 command is:
<ESC> “Q” 60
In BASIC it looks like this:
LPRINT CHR$(27) “Q” CHR$(60);

Each print style is assigned a value to be used with the Master Select com-
mand. The Master Select command consists of <ESC> ’!” followed by a single
ASCII code. To create a Master Select code, add the values of the print styles you
want to combine.
The values of the print styles are as follows:
Elite
1
Proportional
2
Compressed
4
Emphasized
8
Expanded
32
Italic 64
Underlined
128
For example, if you want to find the code for elite emphasized italic print you
would add these values:
Elite
1
Emphasized
8
Italic
64
Master Select code
73
The Master Select Command you would use would look like this:
<ESC> “!” “I”
(I is ASCII 73)
