That must be it. When I first looked at this I checked in the pdf doc
and the new web site just put up at
http://so2.sys-techs.com/mwin/microwin/nxapi/index.html lookiong for
somethig called like it. But, GrClearArea() is not in either docs.
Now I have found it in the source code. Thanks for the info that it does
exist. Exactly what I am looking for.
