	Well, how about this sort of trick:

1. 	Have a file with just a "cd " in it - NO newline on the end (must
	make sure of this)
	call this file \cd.dat

2.	in your batch file do the following

	copy \cd.dat \tmpname.bat
	cd >> \tmpname.bat
	.
	.
	do all your other things
	.
	.
	\tmpname

	That works perfectly under MS-DOS 3.30 at least.

	Basically, cd with no args gives current working directory - make
a batchfile that will take you back there - hence need a cd with no newline.
The files should be in a fixed location as you need to know where they are.
Similar things can be done to save the path etc. Using this you can
have a one level pushdir and popdir written as batchfiles.
