c     "xyzsybyl" takes as input a Cartesian coordinates file,
c     converts to and then writes out a Sybyl MOL2 file
c

      include 'titles.i'
      integer isyb,freeunit
      character*60 sybylfile
c
c
c     get and read the Cartesian coordinates file
c
      call initial
      call getxyz
      write (iout,10)  title(1:ltitle)
   10 format (' Title :  ',a)
c
c     get a list of the bonds in the structure
c
      call bonds
c
c     open a new version of the Sybyl MOL2 file
c
      isyb = freeunit ()
      sybylfile = filename(1:leng)//'.mol2'
      call version (sybylfile,'new')
      open (unit=isyb,file=sybylfile,status='new')
c
c     output the coordinates into Sybyl MOL2 format
c
