Nice try.  You had the right idea.

Here are tested batch files that only use shell commands and COMMAND.COM,
which leave the current directory in the CURRENTDIR environment variable:

For PC-DOS 3.30:
--------------------------------
@echo off
set saveprompt=%prompt%
prompt set currentdir=$p
command/c tmpsetcd>tmpsetcd.bat
prompt %saveprompt%
set saveprompt=
call tmpsetcd
del tmpsetcd.bat
 
For PC-DOS 3.00:
-------------------------------
echo off
set saveprompt= %prompt%
prompt set currentdir=$p
command/c tmpsetcd>tmpsetcd.bat
prompt %saveprompt%
set saveprompt=
tmpsetcd

Note that these batch files work only if you are using a COMMAND.COM that
is NOT patched for turning 'ECHO OFF' automatically.  I couldn't figure out 
how to delete the tmpsetcd.bat file after the PC-DOS 3.00 version.
