PROGRAM list;
uses crt, printer;
æ LIST is a very useful all-purpose list program. It can output å
æ listings of all sorts of text files, with headers, line num- å
æ bers, and full control of page length, line length, left mar- å
æ gin and bottom margin. LIST obtains all its parameters from å
æ the command line. The command line format is: å
æ å
æ LIST <filename><options>,...,<filename><options> å
æ å
æ where <filename> is a file name acceptable to the operating å
æ system, and <options> are one or more options, selected from å
æ the following list: å
æ å
æ Inn Indent each line printed by nn blanks. å
æ Snn Skip nn lines at the bottom of each page. å
æ H Print file name and page number on top of å
æ each page. å
æ Hsssss Print header string and page number on top å
æ of each page. å
æ N Print line number before each line. å
æ F Form-feed. Skip to top of next page. å
æ Tn Tegntype: 1 = Pica, 2 = Elite, 3 = Compressed å
æ An Afstand: 1 = 6 lpi, 2 = 8 lpi å
æ D Dansk tegnsaet å
æ U USA tegnsaet å
æ E Enkeltark å
æ å
æ Each option must be preceded by a forward slash. An example å
æ of a LIST command line: å
æ å
æ LIST WORK.PAS/I8/N/HWorkfile Listing,CALC.PAS,/F å
æ å
æ This line will cause WORK.PAS to be listed with an indenta- å
æ tion (left margin) of 8, line numbers and a user specified å
æ heading. Following this, CALC.PAS is listed using the default å
æ page format parameters, and finally a form-feed is output. å
