If this program is being sent via a modem, saneone at the other end should
enter:
LOAD *“b”
The usual extensions are also possible, such as:
SAVE Y”b”;SCREEN $
and:
SAVE W’b”; LINE number
Sending control codes
Many printers allow you to send instructions for such operations as double
width printing. To send these you should use the b channel. However, with
the b channel, the carriage return does not include a line feed. So you will
have either to change the settings on your printer, or print the line feed
code: 10.
For example, suppose that the control code for double width printing is 14.
Enter:
10 OPEN X4; “b”
20 PRINT* 4; “Normal width”
30 PRINT #4;CHR$14;“Double width”
40
CLOSE #4
(For the correct control codes to use, refer to your printer’s instruction book.1
You can have both b and t channels open at once. Try entering this:
10 OPEN #5:-b”
20
OPEN 3t6;“t”
30PRINT#5;CHR$14;
40LIST#6
50 CLOSE #5: CLOSE #6
This would give you a double width listing.
