RE: [PBML] Taking data directly from memory
- Great, many thanks! I never even thought of using environment variables -
that should work fine for what I'm doing

Maybe one of the Wizards knows a secret, but as far as I know, direct memory
access is contrary to the design of Perl. There are no memory pointers and
no memory address jiggery pokery.
Perl5 *does* have references, which act just like pointers, but you can't
f*(*& them up.
Now with that said, how does your OS save persistent data? Environment
variables? Other? Perl has various options to get and put information
from/to the system using OS-supported mechanisms.
