Programming 3 – 5
Let us try a few, starting with the ASCII non-printable code US. When
the printer receives the SO command, it will print the next data with
double width.
10 LPRINT “HELLO”
20 LPRINT CHR$(14); “HELLO”
Now run the program. This is what you should get:
ASCII code SO is non-printable, so you must use the decimal or
hexadecimal form of the command within a CHR$ statement. Nothing
in quotes will work. Like most commands that change the way the
printer is printing, the SO (double width) command remains in effect
until either the end of a line is reached or you send a command to cancel
it. See what happens if you run the sample program a second time:
