      flag78: points out excessively long lines

      flag78 (fin: in, fout: out, output: out)

      fin: a text file; typically pascal source code.
      fout: the first line of fin followed by a list of the lines which are
            too long.  the list gives the line number of each line, the line
            itself and a flag on the last acceptable character.
      output: the number of lines in fin which contain more than 80 characters.
      during transportation of files from one computer to another, lines
      longer than 80 characters are often truncated to 80 characters to make
      'card images' on the tape.  this byzantine practice is left over
      from the days when cards were the state-of-the-art in talking to
      computers.  since the tape does not know what a 'card image' is,
      and since cards are going the way of the passenger pigeon,
      this is like equipping a nuclear oil tanker with oars.  maybe
      someday things will be different, but until then, flag exists
      and will detect long lines, allowing one to fix a program or file
      before transportation.  note: trailing blanks on each line are

      john hoffhines and tom schneider

      none known

technical notes
      the constant 'maxline' defines the number of characters accepted
      on each line.
