Epson FX-80, User Manual

Page: 60 / 376

Here are two examples of ESCape code sequences:
LPRINT CHR$(27)CHR$(71)
LPRINT CHR$(27)CHR$(38)CHR$(@)CHR$(l)CHR$(3)
To see how such sequences work, start a new program now by
entering:
10 LPRINT CHR$(27)CHR$(52)
20 LPRINT "ITALIC CHARACTER SET"
and RUNning it. When you can RUN a program, we show you the
results that you should expect:
ITALIC CHARACTER SET
Note: If you haven’t yet read the Preface, which includes “Conven-
tions Used in This Manual,” this is the time to do it. Especially
important now are the passages on semicolons and on saving
programs.
The FX interprets the
CHR$(27)CHR$(52)
sequence in line
10
above as
a command to switch from Roman to Italic characters. The LPRINT
in line
20
sends a string of characters to the printer to verify that the
printer is in Italic Mode.
Now type:
LLIST
(or your system’s version of the print LIST
command)
to check the printer’s status as in Figure 2-1:
Figure 2-1. Italic listing
Since all the text is still printed in Italic characters, you can see that this
mode stays on until it is turned off. This is typical of the modes on FX
printers: nearly all modes stay on until turned off. We will alert you to
the few exceptions.
If your printer is printing one line on top of another or if it is double
spacing, you need to change the setting of the FX’s DIP switch
2-4.
