Страница: 50 / 193

Now run the program. You should get the results you see belo w , 10
pi ca c h a r a ct e rs per inch.
Other Pitches
As ex plain e d in Chapter 3 , the LX-80 uses the same pattern o f dots
f or pi ca, e li te, and condensed characters , but it changes the ho rizon-
t al s p aces b e tween the dots to produce the three different w i dths.
I n e l ite m o d e there are 12 characters per inch , and in cond ensed
t h e r e a r e 1 7.16 . The LX-80 prints in elite when it receiv es the
< ESC> M command and prints in condensed when it recei ves the
A S CII 15 co mmand . Print a sample line of elite charact e r s by
a ddin g thi s line to your previous program:
T h is l i n e u ses the comm a nd <ESC> M , to turn on e lit e mode.
Yo u r p r i nto ut should look like this: .
N ow a dd a line to the program to cancel elite with <ESC> P and
turn o n co ndensed with ASCII 15:
3 0 LP I H NT
CHH$(
27)
"P"CHR$(
15) ;
Cancelling Codes
As yo u saw i n the third version of the print pitch program , you must
ca n ce l a co d e when you do not want it any more. With very few
exce ptions , the LX-80 modes stay on until they are cancelled . It is
imp o rt a n t to remember this because an LX-80 mode can s t ay on
eve n if yo u c hange from BASIC to another type of softwar e. For
exa mpl e, i f y ou print a memo with a word processing program after
yo u run th e program above, the printer will still be in cond ensed
m o d e, a nd s o the memo will be in condensed print. To cancel
co n d en se d mode , use ASCII 18.
