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>.
