I was just thinking if commenting your OO-DCL example code. :-)

Yes, the Python implementation use the OO model that Python
is built upon. I have move the Python file that contains the
queue definitions to:

http://jescab2.dyndns.org/pub_docs/queues.py

so you can study how it is implementet. That file is what is
read by my first command in my example, "from vms import queues".
That "loads" the queue definitions and functions into Python.

As you can see, the higher level functions are built on the
interface to getquiw() that is included in the "starlet"
part of the VMS module for Python.

The "starlet" module has quite a few of the common system
services implented and directly usable from Python. Doing

import vms.starlet
help (vms-starlet) gives a list of functions directly
callable from the VMS port of Python:

In many cases higher level funtions has been created like
