title: How to get the cmd window's height (in lines)?
body: <p>I want to do a personalized "more" command where the lines are output page by page. 
  Therefore, I need to get the height of the windows in a variable, in an unit of lines.
  Is there a way to do that simply in a batch file?</p>
  
  <p>Else, how could I use the more command (or a similar one), but with a header to see a kind of title bar at each page echoed?</p>
