Chapter 1 Introduction to PRESCRIBE TEXT "You're about to enter PRESCRIBE."; TEXT ' " " " '; In the first command above, the character string starts with a double quotation mark. The printing system therefore expects the string to end with a double quotation mark, and regards the apostrophe in the word You're as an ordinary character, not as the string terminator. Similarly, the double quotation marks in the second command above are recognized as ordinary characters, not as string terminators. Since an apostrophe or quotation mark can start a character string anywhere in a PRESCRIBE command sequence, it is important not to start character strings unintentionally. The following examples demonstrate incorrect use of apostrophes and double quotation marks. Incorrect: !R! CMNT Don't leave stray apostrophes; EXIT; Incorrect: !R! CMNT The symbol " means inches; EXIT; In both of the above cases, the printing system assumes that the expression EXIT; is part of a character string started by the preceding apostrophe or quotation mark, and fails to exit the PRESCRIBE mode. The correct way to write these comments is: Correct: !R! CMNT "Don't leave stray apostrophes"; EXIT; Correct: !R! CMNT 'The symbol " means inches'; EXIT; Character strings must not exceed the 255-character limit on total command length. If a character string exceeds this limit, the printing system terminates it forcibly and begins looking for the next PRESCRIBE command. Upper and Lowercase Letters Regarding upper and lowercase characters, PRESCRIBE follows the same rule as many computer programming languages: it discriminates case inside character strings and ignores it elsewhere. You can type command names in upper or lowercase. Correct: !R! TEXT 'A'; CIR 1; EXIT; Also correct: !R! text 'A'; cir 1; exit; Also correct: 1-12
