Expanded Mode

Perhaps the most dramatic mode on the LX-90 is expanded. It pro-

duces extra-wide characters that are good for titles and headings. For

this mode, the dot pattern of each character is expanded and twice as

many dots are printed. You can see the difference between pica and

expanded pica if you enter and run this program:

PRINT CHR$(4);"PR#l"

10 PRINT "This is standard printing."

20 PRINT CHR$(27);"W1";

PRINT "This is expanded."

100 PRINT CHR$(27);"@"

300 PRINT CHR$(

4);

"PR#0"

This is standard printing.

This is expanded-

For this mode the letter W and

the

numeral one together turn

the

mode on and the letter W and the numeral zero together turn it off.

Thus ESCape “W1” turns

expanded and ESCape "WO” turns it off.

Those of you who are programmers may be interested in another

form of expanded. In this alternate form, called one-line expanded,

the printing is the same as that in the example but it is turned on by

ASCII 14 and is turned off by a line feed, ASCII 20, or ESCape "WO”.

Mode Combinations

You can also use control codes to combine modes. For example, you

can make a title especially vivid by combining emphasized and

expanded. In fact, you can combine nearly all of the print modes on

the LX-90; your LX-90 printer can print such complicated combina-

tions as double-strike emphasized expanded underlined subscript,

although you may never want such a combination. The point is, how-

ever, that the LX-90 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 expanded, change two lines in

your previous program:

20 PRINT CHR$(27);"W1";CHR$(27);"E";

30 PRINT "Emphasized expanded"
