There is a simple way to do something similar to this, although it really isn't
a solution, just a patch, but it doesn't take too much effort, and may be
adequate for what you want.

Use the SUBST command to assign a logical drive, say x:(assuming you have
included a line "lastdrive=z" in your config.sys) to the other directory you
want(or just the same drive and feed it the path).  Then change drives(just
"x:").  DOS remembers the current directory in each drive, so when you come
back c:(assuming you just work off c:, otherwise, this won't work), you will
still be in the old directory.

I have used the same trick to do a whereis on just a subdirectory tree.  The
public domain version of whereis we have searches the entire disk(if there is
another version that accepts a path, I'd like to hear about it.)  The batch
file looked something like the following:

if "%2" == "" goto usage
subst x: %2
x:
whereis %1
c:
subst x: /d
goto end
:usage
echo Usage: whis file path
:end
