+C  F77CONE -- Fortran example task of VOClient interface
+C
+C  M.Fitzpatrick, NOAO, Jul 2006
+
+	program f77cone
+
+	double precision ra, dec, sr
+	character service*80
+
+C  Initialize values.  Note the VOClient library assumes all floating
+C  point values are double precision.
+	ra  = 12.0d0
+	dec = 12.0d0
+	sr  = 0.1d0
+	service = "http://www.nofs.navy.mil/cgi-bin/vo_cone.cgi?CAT=USNO-B1&"
+
+	call coneservice (service, ra, dec, sr)
+
+	stop
+	end
+
+
+C  Simple test routine to call a Cone search service and summarize results.
+
+	subroutine coneservice (service, ra, dec, sr)
+
+	character*80 	 service, fmt, sid, sra, sdec
+	character*160    attrlist, qstring
+	integer		 nrec, nattr, len, ier, index
+	integer		 cone, query, qr, rec
+	double precision ra, dec, sr
+
+
+C   Initialize the VOClient
+	call vfinitvoclient ("", ier)
+
+C   Get a new connection to the named service and form a query.
+	call vfopenconeconnection (service, cone, ier)
+	call vfgetconequery (cone, ra, dec, sr, query)
+
+C  Print the query string we're about to execute.
+        index = 1
+        call vfgetquerystring (query, 3, index, qstring, len)
+        print *, "Executing Query: "
+        print *, qstring
+        print *, ""
+
+
+C  Execute the query, get back a response handle 'qr'.
+	call vfexecquery (query, qr)
+
+C  Now summarize the response.
+	call vfgetrecordcount (qr, nrec)
+	if (nrec <= 0) then
+	  print *, "No records matched"
+	  return
+	endif
+
+C  Get a sample record so we can summarize columns.
+	call vfgetrecord (qr, 1, rec)
+	if (rec > 0) then
+	    call vfgetattrcount (rec, nattr)
+	endif
+
+	print *, "# returns ", nrec, " records of ", nattr, " attrs"
+	print *, "#"
+	print *, "# --- Summary output ---"
+	print *, "#"
+
+C  Get the list of attributes.  Note that when receiving a string value
+C  the interface requires you specify the max length of the string and
+C  will return the actual length of the string.
+	call vfgetattrlist (rec, attrlist, len)
+	print *, "# ", attrlist
+	print *, "#"
+
+
+C  Summarize and print selected query results.  Note the results table
+C  is one-indexed in this interface.  We also show how to catch an invalid 
+C  record descriptor.  To try this, change the starting index to 0 instead
+C  of 1.
+
+	do i = 1, nrec, 1
+
+C	  Get the row in the table and then select values to print
+	  call vfgetrecord (qr, i, rec)
+	  if (rec > 0) then
+	      call vfgetstringattr (rec, "ID_MAIN", sid, len)
+	      call vfgetstringattr (rec, "POS_EQ_RA_MAIN", sra, len)
+	      call vfgetstringattr (rec, "POS_EQ_DEC_MAIN", sdec, len)
+	  else
+	      print *, "Error getting record number: ", i
+	      goto 100
+	  endif
+
+	  fmt = '(i3,a6,a18,a6,a18,a6,a18)'
+	  write (*, fmt)  i, "  id= ", sid, "  ra= ", sra, "  dec= ", sdec
+	enddo
+100	continue
+
+
+C  Close the connection and shut down the VOClient server.
+	call vfcloseconnection (cone)
+	call vfclosevoclient (1, ier)
+
+	return
