To generate an 8-level contour plot of a $50\times 50$ pixel region centered on the cursor.

  pr> eimexam                                # put parameter file in editor, set
                                       # ncolumn = 50, nlines = 50, ncontour = 8

Set parameters by moving cursor to appropriate row.

  ctrl x                                                       # to leave editor
  pr > = ``stdgraph''                 # for display on screen


  pr> = ``stdplot''                          # for hard copy
  pr> imexamine xdata$rp110590_im1
