      SUBROUTINE PGSCH (SIZE)
      REAL SIZE

 Set the character size attribute. The size affects all text and graph
 markers drawn later in the program. The default character size is
 1.0, corresponding to a character height about 1/40 the height of
 the view surface.  Changing the character size also scales the length
 of tick marks drawn by PGBOX and terminals drawn by PGERRX and PGERRY.

 Argument:
  SIZE   (input)  : new character size (dimensionless multiple of
                    the default size).
