the
FX-286;
your
FX-286
printer can print such complicated combina-
tions as double-strike emphasized double-width underlined subscript,
although you may never want such a combination. The point is, how-
ever,
that the
FX-286 has the ability to produce almost any combina-
tion you can think of; it’s up to you to decide which ones you
want
to
use.
To see emphasized combined with double-width, change two lines
in your previous program:
20 LPRINT CHR$(27)"W1"CHR$(27)"E";
30
LPRINT "Emphasized double-width"
When
you run the program, your printout should match the one
below, showing that
the two
modes combine with
no
trouble.

A later section in this chapter explains a special Epson mode
ESCape code, Master Select, which allows you to control seven fea-
tures with one ESCape sequence.
Underline mode
The
FX-286
also has a mode that will underline characters and
spaces. You turn it on with ESCape “-1” and off with ESCape
"-0".
Note that the underline code is like the double-width code in that it
uses a character, in this case the hyphen or minus sign, combined with
the
numeral one to turn it
on
and a character combined with the
numeral zero to turn it off. You can see it in action with
the
following
program:
NEW
10 LPRINT "This text is not underlined."
20 LPRINT CHR$(27)"-1";
30
LPRINT "This text is underlined."
This text is not underlined.
T h i s t e x t i s u n d e r l i n e d .
As shown in the printout above, the underline mode is continuous,
but some word processing and other applications programs produce
5-10
