1 HEADER
        HEADER

    A (not so) simple minded routine to list edit and modify the  header  of
    a  GDF-like file (Image only, Table edition is usually meaningless).  It
    is functionnally equivalent to command "HEADER File"  in   the   GRAPHIC
    program.



    On some systems, editing of header parameters is possible  if  you  have
    write access to the image.

      -  To modify a header parameter, position the   cursor   on   it   and
        press   key Gold (PF1).  You can then enter the new value.  When you
        are happy with the modified value, press Enter.
      -  To compute the extrema of the image, press key Enter.
      -  To exit from the edit mode, type <^Z>.
