In this program, you can use any number you calculate by using the formula above, but remember that emphasized can’t combine with compressed or elite. If you try to combine emphasized with either of the two narrow pitches, you won’t harm your printer; it will simply use a priority list in its memory to determine which mode to use. The list below shows the results of trying to combine emphasized with either or both of these modes.

Emphasized + compressed + emphasized
Emphasized + elite + elite

 

Emphasized + compressed + elite

compressed elite

Master Select is a powerful code that gives you an easy way to produce multiple combinations with a single command. To see double-strike emphasized underlined printing, for example, you need only one ESCape code instead of three.

Indeed, Master Select is such a powerful feature that it may occasionally be more powerful than you want it to be. Because it controls seven different modes, a Master Select code will cancel any of those seven that are not selected. For example, suppose that you have a page in elite and want part of it in double-strike. If you use ESCape "I" 16 to turn on double-strike, your LX-90 will begin printing in double-strike pica instead of double-strike elite because the 16 code does not include elite. Use 17 for double-strike elite.

Superscript and Subscript

Your LX-90 can also print superscripts and subscripts, which you can use for mathematical formulas, footnotes, and other items that require numbers or letters above or below the usual print line. ESCape “SO” turns on superscript and ESCape "Sl" turns on subscript. ESCape "T" turns off either one. You can see them in action with the program below:

10 LPRINT "The formula for water is H";20 LPRINT CHR$(27);"Sl";"2";CHR$(27);"T";30 LPRINT "0."40 LPRINT CHR$(27);"@"
