UNSUPPORTED

 WARNING:   Each  widget  or  gadget  supports  a  specific  set   of
 arguments,  reasons, and children.  The particular argument, reason,
 or child you specified is not supported for this widget or gadget.

 USER ACTION:  See the UIL built-in tables  in  the  "VMS  DECwindows
 User   Interface  Language  Reference  Manual"  for  the  arguments,
 reasons, and children supported for each  object.   If  a  low-level
 creation routine accepts an argument that UIL rejects, this does not
 necessarily indicate that  the  compiler  is  in  error.   Low-level
 routines   ignore  arguments  that  they  do  not  support,  without
 notifying you that the argument is being ignored.
