      SUBROUTINE GRCHR0 (WINDOW,CENTER,ORIENT,ABSXY,X0,Y0,STRING)

 GRPCKG (internal routine): Support routine for GRCHAR and GRMARK.
 Draw a string of characters.

 Arguments:

 WINDOW (input, logical): if .TRUE., the plot is windowed in the
      current window.
 CENTER (input, logical): if .TRUE., the first character of the string
      is centered at (X0,Y0); otherwise the bottom left corner of the
      first character is placed at (X0,Y0).
 ORIENT (input, real): the angle in degrees that the string is to make
      with the horizontal, increasing anticlockwise.
 ABSXY (input, logical): if .TRUE., (X0,Y0) are absolute device
      coordinates; otherwise they are world coordinates (the scaling
      transformation is applied).
 X0, Y0 (input, real): position of first character (see CENTER).
 STRING (input, character): the string of ASCII characters; control
      characters 0-20 have special representations; all other
      non-graphic characters are plotted as blank spaces.
