SD - Set directory

        SD is like CD except that before changing it saves the current
        directory name in the MS-DOS environment.  The command

                SD;

        can be used to return to the previous directory.  A naked

                SD

        not only shows the current directory, but the return directory
        as well.  Successive SD;'s can be used to toggle back and forth
        between two directories.

        Also

                SD A:SNERD

        implies

                SD A:\SNERD
        
        and

                SD A:

        implies

                SD A:\

        (use

                A:

        if you want to return to the remembered directory on
        another drive).

	A final feature: if the given directory does not exist, a
        backslash is prepended and the command retried.  For example,

                SD PLOP

        implies

                SD \PLOP

        if PLOP is not a subdirectory of the current directory.

        To use SD, first copy SD.EXE to the root directory, insert the
        following into AUTOEXEC.BAT, and reboot:

                PATH C:\
                SET SD=C:\ XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

        where C is your boot disk.  The number of X's is not critical
        but should be as large as the longest directory name you will
        use.  The space before the first X is necessary.

        The PATH command is necessary so you can put SD.EXE in the root
        directory on C and execute it from any directory.  Of course,
        you may put it elsewhere if you like as long as PATH is such
        that it can be found.
