/*
This uses $LK,"DocPrint","MN:DocPrint"$() because updates
to within a tree while a tree is collapsed get
messed-up if "live" (like using ordinary Print.)
The insert point is confused by hiding of
data in collapsed trees. Therefore, the window main
Doc is taken off-line by disabling preemption so there
are no screen updates until all data has been inserted.
There is a special Doc function which is also
available to take an Doc off-line. See $LK,"DocInsSafe","MN:DocInsSafe"$.
For this example, however, I wanted to use DocPrint
and disabled Preemption myself.
