          Purpose:  Provides a way to return automatically to
                    your current directory after running programs
                    that require directory changing.

          Format:   PUSHDIR
                    [CD \AltDir\ProgName]
                    POPDIR

          Remarks:  While PUSHDIR and POPDIR can be entered
                    directly from the DOS prompt, their primary
                    application is in batch files.  For example,
                    suppose you create a file named 12.BAT that
                    consists of the following four lines:

                         PUSHDIR
                         CD\LOTUS
                         123
                         POPDIR

                    Suppose also that 12.BAT, PUSHDIR.COM, and
                    POPDIR.COM are either in your root directory
                    or in a subdirectory on the PATH specified in
                    your AUTOEXEC.BAT file.  Assume, finally,
                    that you are currently in your word
                    processing subdirectory (\WP), but need some
                    information from a 1-2-3 spreadsheet.  If you
                    now enter

                         12<CR>

                    from the DOS prompt, PUSHDIR stores the \WP
                    (your current directory) on its stack and DOS
                    changes to the \LOTUS subdirectory and runs
                    1-2-3.  When you exit from 1-2-3, you would
                    normally be left in the \LOTUS subdirectory.
                    A DOS CD command in 12.BAT after the 123 line
                    could return you to a specified directory
                    every time you terminated 1-2-3, of course.
                    But POPDIR returns you to whatever
                    subdirectory you were in when you invoked 1-
                    2-3--in this case, to your \WP subdirectory.

                    PUSHDIR can accommodate up to six levels of
                    directories on its stack, permitting
                    considerable programming flexibility in
                    constructing batch files.

                    Notes:

                    1.   PUSHDIR and POPDIR require DOS 2.0 or
                         later.
