Well, there is the command-line tool 'set'.
So, if you have a batch file for the program you want to run:
(Assuming that there is a bin folder and a include folder inside the
directory you run the batch file from)
<runmyprog.bat>
set PATH="%PATH%";"%CD%\bin"
set EUDIR="%CD%\bin"
set EUINC="%CD%\include"
set MYPROGRAMSTUFFLOCATION="%CD%\myprogram\myprogramsstuff"
exw myprogram\myprogram.exw
</runmyprog.bat>

(%CD% is a batch file thing containing the current directory.)


Now, the set command only sticks for the current session, so if you
use set in a batch script, it's effects are only felt within that
script. If you want to have a batch file that you run on connecting
the drive, and from then on everything works fine, then use setx - you
need more priveleges to use the command, but it is a permanent
addition.

Hope that helps...
