title: How to modify the paper dimensions in plain TeX?
body: <p>I mean the whole paper, not only the text zone in it.</p>
  
  <p>I want the dvi output to look 1 centimetre x 10 metres in the viewer if
  I set these dimensions in the tex file.</p>
  
  <p>And I don't want to go through LaTeX for it.</p>
