St r.:1n clar · d Pr · i nt Figure 5- 3 Standard and enlarged characters You can try enlarged yourself by using the code "Wl" in the master program. Notice that enlarged mode uses an ESCape code format that is slightly different from the previous ones. You must use the numeral as well as a capital W to turn on enlarged. For this mode the letter and the numeral together turn on the mode and the letter and the numeral together turn it off. Thus ESCape "Wl" turns on enlarged and ESCape "WO" turns it off. Programmers may be interested in another form of enlarged mode.
In this alternate form, called one-line enlarged, the printing is the same as thac in Figure 5-3, but it is turned on by ASCII 14 and is turned off by a line feed, ASCII 20, or ESCape "WO". Mode Combinations By now you're probably wondering how to combine modes using con- trol codes. For example, can a title be made especially vivid by combin- ing enlarged and emphasized? The answer is that you can combine nearly all of the print modes on the MPS 1000. Indeed, your MPS 1000 printer can print such complicated combinations as double-strike emphasized enlarged underlined subscript, although we're not sure you would ever want to use such a combination.
The point is, however, the MPS 1000 has the ability to produce almost any combination you can think of; it's up to you to decide which ones you want to use. To see a few combinations, remove line 90 from the master program. Now run the program once and enter "E" and "emphasized" in response to the questions on the screen. This will give you the same results as the first time you ran the program, but it will leave the printer
