And for the programs in this manual, don’t forget to use PRINT #l

wherever we use LPRINT.

This won’t work for those of you who have the original release of

the Disk Operating System (DOS 1.0). It can’t run a printer like a file.

IBM has, however, issued a free update (DOS 

1.05); 

take a disk to

your dealer to get your copy.

Another printer problem with DOS 1.0 is that it doesn’t send

CHR$(7) to the printer; it just rings the computer’s bell. This has also

been corrected in subsequent versions.

QX-10™ 

There are two types of computer-printer interface problems that

you owners of Epson QX-10s may need to address. The first is

making a width statement when a line is to be more than 80 characters
wide. The second is changing any occurrence of the number nine to
some other number.

Any time you want to print more than 80 characters (or more than

130 dot columns in graphics) on one line, you need to reserve the

extra room by putting the WIDTH statement:

WIDTH 

 255

in one of the first lines of the program.

The only problem code for the QX-10 is 9. One way to get around

this is to use the ASCII high-order equivalent (137) whenever you
would normally use 9.

Sometimes it may be easier to use another low-order value. For

example:

 

 

 

 

 

 

   

 

When DATA numbers include 9, you can change each 9 to 8 or 11.

The best number to substitute for 9 in pin patterns is usually 11.
