Double-width Mode
Perhaps the most dramatic mode on the LX-86 is double-width.
It produces extra-wide characters that are good for titles and
headings. For this mode, the dot pattern of each character is
expanded and a duplicate set of dots is printed one dot to the
right. You can see the difference between pica and double-width
pica in Figure 6-3.

You can try double-width yourself by using the code
“W1”
in
the master program. Notice that double-width uses an ESCape
code format that is slightly different from the previous ones. You
must use the numeral one as well as a capital W to turn on double-
width. For this mode the letter and the numeral one together turn
on the mode and the letter and the numeral zero together turn it
off. Thus ESCape “Wl” turns on double-width and ESCape
"Wo”
turns it off.
Those of you who are programmers may be interested in
another form of double-width. In this alternate form, called one-
line double-width, the printing is the same as that in Figure 6-3,
but it is turned on by ASCII 14 and is turned off by a line feed,
ASCII
20,
or ESCape
“WO”.
