Name: SYMFIL  1
A metafile can be converted with a driver  program and sent from
the operating system to several devices. From within a user pro-

The call is:  CALL SYMFIL (CDEV, CSTAT)                  level 0
         or:  void symfil (char *cdev, char *cstat); 
CDEV          is the name of the device.  'CONS'  refers  to the
              graphics screen,  'XWIN'  to an X Window terminal,
              'PSCi' to a PostScript printer,  'KYOi'  to a Kyo-
              cera  laserprinter with Prescribe, 'HPLi' to a HP-
              plotter and 'METi' to output for a colour graphics
              system,  where i = 1, 2, 3, ..., n is the  printer
              number. The keyword 'NONE' deletes a metafile with
              no device plotting.
CSTAT         is a status parameter and can have the values 'DE-
              LETE' and 'KEEP'.

         or:  void incfil (char *cfil);
CFIL          is a character string that contains the filename.
Notes:      - The routine  FILBOX defines a rectangular  area on
              the page where the metafile will be included.
            - The routine FILCLR sets an option to ignore colour
              values in the metafile.
Name: FILBOX  1
The routine FILBOX defines a rectangular area on the page  where
metafiles will be included by the routine INCFIL.
The call is:  CALL FILBOX (NX, NY, NW, NH)         level 1, 2, 3
         or:  void filbox (int nx, int ny, int nw, int nh);
NX, NY        are the plot coordinates of the upper left corner.
NW, NH        are the width  and length of the box in plot coor-
              dinates.
                          Default: The entire page will be used.
Name: FILCLR  1
The routine  FILCLR can be used to ignore colour values in meta-
files included with the routine INCFIL.
The call is:   CALL FILCLR (CMOD)                  level 1, 2, 3
         or:   void filclr (char *cmod); 
CMOD           is a character  string  that can have  the values
               'ALL' and 'NONE'.          Default: CMOD = 'ALL'.
