EXAMPLES ________
Two examples of the operation of the Return Stack in the
multiple window version follow:
Example 1:
The current window is #1. Window 2 is blank.
1 2

------------------
-------%J1--------
------------------
------------------

User types 'J/%'. Result is:
1 2

------------------ %P1---------------
--------%J1------- ------------------
------------------ ------------------
------------------ ------------------

At this point, no locations have been saved in the return stack,
as explained above. Issuing RETURN would produce the message 'NO
MORE RETURN POINTS' and the display will remain unchanged.
Example 2:
The current window is 1.
1 2 3

%J1----------- text1--------- text2---------
-------------- -------------- --------------
-------------- -------------- --------------

User types 'J/%'. Result is:

%J1----------- %P1----------- text2---------
-------------- ----%T-------- --------------
-------------- --------%J2--- --------------
