-ML182/183 ________________ _-Computers cannot understand letters. They use only numbers, morespecifically, binary numbers (1 s and as). When carrying out anLPRINT command, the computer s.ends the printer a code numberfor each character (letter, symbol, punctuation mark) within thequotation marks. As the printer receives each number, it prints thedot pattern associated with that number.The American Standard Code for Information Interchange (before -known as ASCII) is the standard code used by computers. AppendixD gives the ASCII code numbers along with their hexadecimal, -binary, and decimal equivalents. You can enter these ASCII numbersdirectly in your LPRINT statement by using the CHR$ (Character -Stri ng) function.-The CHR$ command sends the ASCII command in parentheses tothe printer. For example, we can write a program this way:LPRLI;:-lT· CHR$(79);CH R$(75);CHR$(73);CHR$ (68);CHR$(65);CHJ!$<84); OtfR$ (65) . ;,:::",;'.. ... ,)h -This is obviously a tedious way to write, but you need to understandthe concept when you want to use certain commands.Keep in mind that there is a big difference between ASCII code -numbers and numbers that are printable characters. For example, ifyou want to print the number 1 using an LPRINT statement, youwould type this:LPRJ,,Il>jTCHR$(49)You can also print numbers and symbols by putting them withinquotes, like this:-[PRINT"1 "So far, we have discussed printable characters, ASCII codes locatedbetween decimal 32 and decimal 127. Non-printable codes, locatedbetween a and 31, do not tell the printer to print something. Theyinstruct the printer how to print something. The ASCII chart in theback of this handbook shows that these codes have abbreviations,such as FF and US. Some of these abbreviations make sense (FF, forinstance, stands for form feed) but others do not unless you are atelecommunications expert.-40
