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.
