More complex commands consist of two or more character
codes. For example, to print in proportional mode the code format
is:
ASCII code:
ESC
p
Decimal:
27
112
:
Hexadecimal:
1B
70
n
In this case
n
can be either 1 or 0, to begin or end proportional
printing. To turn ON proportional printing from BASIC the
command is:
LPRINT
CHR$(27);CHR$(112);CHR$(l)
Control key chart
Some application programs can use control key codes for decimal
values O-27. The table below gives you the proper values. The
Control Key column indicates that you press the control key at the
same time you press the key for the letter or symbol in that column.
For example, you press the control key and A at the same time to
send the value 1.
Some programs that use this system cannot use control-@, and
many programs use the control keys for other purposes.
