       SUBROUTINE  SYMJU (STRATR,BOXATR)
 C$    (Text Justification Attributes)
 C$    When text strings  are plotted,  it is often  useful to  be
 C$    able to  simply  achieve right-justification  or  centering
 C$    about a point without burdening the user with the necessary
 C$    calculations.  Normally, text is plotted starting from  the
 C$    current point  along  the  requested  character  path,  and
 C$    individual character  boxes  are  lined up  such  that  the
 C$    baseline corresponding to the bottoms of upper-case letters
 C$    lies along the path.
 C$
 C$    The entire text string may  be justified along the path  by
 C$    selecting one of the following string attributes:
 C$
 C$    "FIRST"  - Current point denotes position of first
 C$               character to be drawn.
 C$    "OFF"    - Same as "FIRST".
 C$    "CENTER" - Current point denotes position of center of text
 C$               string parallellogram.
 C$    "LAST"   - Current point denotes position of a character
 C$               which would  follow  the last  character  to  be
 C$               drawn.
 C$
 C$    To move  individual character  boxes perpendicular  to  the
 C$    path, a  box  justification  attribute  may  be  chosen  as
 C$    follows:
 C$
 C$    "BOTTOM" - Boxes shifted so that descenders of lower-case
 C$               letters g, p, q, and y just touch the path.
 C$    "OFF"    - Boxes aligned with upper-case baseline lying
 C$               along path.  This is the default.
 C$    "CENTER" - Boxes aligned with symbol centers lying along
 C$               path.
 C$    "TOP"    - Boxes aligned with tops of upper-case letters
 C$               lying along path.
 C$
 C$    The default  positioning corresponds  to (STRATR,BOXATR)  =
 C$    ("FIRST","OFF").  A  string  will  be  centered  about  the
 C$    current  point   if   ("CENTER","CENTER")   is   requested.
 C$    Right-justification (as for digits  along a vertical  axis)
 C$    is requested by ("LAST", "OFF").
 C$
 C$    These strings are  provided as the  arguments "STRATR"  and
 C$    "BOXATR".  Only the first character is significant and will
 C$    be tested, but more may  be of course provided.  Thus  "F",
 C$    "FI",  "FIRST",  and  "FOO"  will  all  be  interpreted  as
 C$    "FIRST".   The  arguments  may  be  either  upper-case   or
 C$    lower-case.
