   More on the window problem.  I repeated several earlier experiments, this
time making sure I had first got rid of /term.  As I mentioned in an earlier
posting the BASIC09 programming example for select works OK.  There still
are problems when I try to make a similar experiment work with the display
command.  The main symptom is that the entire screen clears to a grey shade
and then you have to hit clear to get back to the original window.  After
that, clear seems to work correctly.  In particular the grey screen doesn't
reappear as a result of hitting clear again.  In the "display" version of
the experiment I had to use several display commands strung together with
semicolons to allow output to be redirected to different windows. Each display
is therefore a different task and the various paths to windows are being
closed and reopened in this case.  This may account for the difference in 
result from BASIC09.
