It is neither possible in unix. When you run a batch script under Win32, or 'source' a shell script under unix, you only have 1 process, and that process is executing commands, which set _its_ env variables.
If your fork a child process (ie. start perl to execute the perl-script), it can only change its own env, it cannot change the env of any other processes (including its parent).
