1.$ PMDF PS THESIS.TXT

      In this example, the name of the output file is omitted.
      Consequently, the output will be stored in a file named
      thesis.ps.

    2.$ PMDF PS/FONT=BOOKMAN-LIGHT THESIS.TXT

      This command illustrates the use of the /FONT qualifier to
      select an alternate font.

    3.$ PMDF PS/COLUMNS=2/LANDSCAPE/SIZE=8 THESIS.TXT

      This last command shows how to format the file THESIS.TXT
      for printing in two columns. When more than one column is
      requested, use of the /LANDSCAPE qualifier is recommended.
      Furthermore, the font size should be reduced with the /SIZE
      qualifier so as to keep lines of text from running into
      adjacent columns or off of the page.
