Help for REALLIST

PURPOSE:
      REALLIST produces a listing of a REAL*4 VICAR dataset. It is a limited
version of list, with a different output format.  If possible, values are
printed in decimal notation. Exponential notation is used only when decimal
values will not fit within the columns.  In the default mode, the image is
printed in strips that are six pixels wide. If WIDE is specified the strips
are 10 pixels wide and require wide screens and paper.
