To set the Message Window enahancements, you can set the Window Enhancement
parameter of the VPUTWINDOW intrinsic.  The values for this area are given in
the
description of the common area (pg 6-13 of my manual) of the VPLUS manual.  We
have
an application that uses 'C' or '67' for inverse blinking at a point where the
user
is waiting on a long process to finish.
 
Be sure to set the enhancement back to '@' or '64' (Stop Enhancement) after
this
call.
