in emphasized mode so that you can add another mode. Then run the program again (without turning off the printer). The second time enter "Wl" and "emphasized enlarged." Your printout should be in the typestyle below, showing that the two modes combine with no trouble. You can experiment with other combi- nations if you wish or you can wait for the section later in this chapter that explains a special ESCape code, Master Select, which allows you to combine as many as seven features with one ESCape code. E:o m p h ..a -s. i :z E:o c::I When you are through trying combinations, be sure to replace line 90 in the master program so that you can again try one feature at a time.
Underline Mode The MPS 1000 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 enlarged code in that it uses a character, in this case the hyphen or minus sign, combined with numeral 1 to turn it on and a character combined with the numeral 0 to turn it off. As you can see in Figure 5-4, this mode prints a dot in the bottom row of each column, producing a continuous underline . This uses the underline mode. Figure 5-4.
Underline mode As shown in Figure 5-4, the underline mode is continuous, but some word processing and other applications programs produce an underline that leaves spaces between characters as demonstrated in the printout below. 67 1• 1• • 1• 1• • 1 1• - u -- • • • - -- • - 1•1 I l n• ·- •
