@b<This window will tell you how the ASSIST controls the potentially large number of windows that can be created.>

In order to manage the large number of windows that the ASSIST can
create, a @b<Window Management> scheme has been implemented.  Under
this scheme, users can specify the contents and placement of one or
more stacks of windows, and can also specify the maximum number of
windows that can be placed in each stack.  The ASSIST will then
place each window it creates into one of these stacks.  When a stack
has reached its maximum window depth, the first window entered into
the stack is removed to make room for a new window.  In this way, the
number of windows displayed at any one time is under user control.
By default, graphers are placed in one stack, parameter editors are
placed in another, help windows in third, tutorials in a fourth, etc.

Individual windows can be @b<locked> so that they are not removed in
order to make room in the stack for new windows.

To learn about how to lock windows in a stack:
@button<Locking Windows, Stack_Locking>
