For example, in BASIC you can turn on double-width with

either of these statements:

 

LPRINT

CHR$(27);“W”;CHR$(l) ------

ASCII code

LPRINT

CHR$(27);“W”;“l” -------------

ASCII character

These BASIC commands correspond to the printer commands below:

ESC W SO or ESC Wl

Control key chart

Some application programs can use control key codes for decimal values 0 through 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.

Note: Many programs use the control keys for other purposes. Also, some programs do not use all of these keys.
