You
use

to
control whether the display
IS
a single window or
is
split into
two windows which can be used
to
show two separate portions of the grid.

a honzontal

(J)
a split display back
Into
a single window.
If
the window
IS
initially split and you want
to
change from,
say,
a horizontal
to
a vertical split you must first join the two windows
before
making
the
new
split
If
you choose
to
split the window then the split
