# This file provides compatible implementation of Icon 8.10 functions
# that cannot be replaced with 9.0 functions via the simple renaming
# done in xnames.icn. The following procedures are provided:
#
# XBind(w1, w2, ...)
# XUnbind()
# XWindowLabel(s)
# XDrawArc(w,x,y,width,height,a1,a2,...),
# XFillArc(w,x,y,width,height,a1,a2,...),
#
############################################################################
#
# Requires: Version 9 graphics
