As you has been told to set an environment variable assign to the
%ENV hash. But the way you write it I suspect that you want to set
an environment variable in the shell (or other process) you called
the script from, using that script. And that's something that can't
be done, you can only set an environment variable for the process
you're currently running (and for the child processes it may start
later) but never for its parent process, i.e. the process that
started the script.

1. Enter "perldoc perlfunc".

2. Scroll downwards til you find a section with "Functions for real
%HASHes".

3. The function "delete" sounds promising, right? Enter
"perldoc -f delete" to get more info about it.

4. Yep, that seemed to be it. :)
