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.
