• R Return ______________
RETURN moves the display buffer to the last display point saved
on the Return Stack.
Return <wind>°
NOTES _____
• The Return Stack is a list of up to 64 display points
constructed on a LIFO (last in - first out) basis. When RETURN
is issued, the display moves to the display point on top of the
Stack (the last one added).
• The current display point is added to the Return Stack whenever
a FRESS command causes the display to move non-linearly
(DSPACE, GLABEL, JUMP, BOTTOM, MOVE in Transcription Mode,
GFILE, and MFILE commands).
• The current display point can be saved explicitly, using the
SAVE command.
MULTIWINDOW ___________
replaced • A display point is saved only if it is ________ by the results
of a non-linear travel other than a RETURN. That is, if a
GLABEL from window 1 causes the text which was in window 2 to
be replaced by the specified label and following text, the
display point from window 2 would be saved in the LIFO stack.
• If a window number is specified, the return point will be
displayed in that window.
• If no window number is specified, the system will try to place
the return point in the window in which it originally appeared.
If this is not possible (i.e., the window no longer appears on
the screen), another window will be used.
• The window in which the return point is displayed becomes the
current window.
