@b<This window will tell you about the ASSIST resources that are used to control the number of windows on your screen.>

In order to manage the potentially large number of ASSIST windows,
each one is assigned to a @b<stack> The @b<maxonScreen> resources
specify the depth of each window stack.  After a stack reaches the
maximum number of windows, newly created windows will cause older
windows to be closed, on a first-in, first-out basis.  Thus, the
number of windows in a stack will remain constant.  Note that when
windows are closed, the new windows are still displayed at the top of
the stack, rather than being placed in the position of the closed
window. (We thought it would be too disruptive if windows were
constantly changing place).  Placing window are the "end" of the stack
will cause "holes" to appear in the stack.  The @b<tidy windows> menu
item in the top-level window will remove the holes and place all
windows back in an orderly display.

Individual windows can be @b<locked> so that they are not closed in
order to make room for new windows in a stack.  This is done using
the @b<locked> resources, as shown below.  Locking windows will have
the effect of temporarily increasing the depth of the stack, if more
windows are locked than the stack would normally allow for.  Windows
can also be locked and unlocked using the @b<Lock> command in a
parameter editor.

Example resources are shown below.
