When you understand the concept of software memory segmentation in the 
APIs, you'll probably better understand the references.

Try to create a 64-bit everything-in-P2-space app. Not a post-V7.0 P0 
app with P2 data, but everything related to the app in P2 space. 
It's... illuminating.

OpenVMS increasingly reminds me of working on PDP-11 / RSX-11M, where 
you have to be centrally aware of and working around memory addressing 
limits whenever working on a larger app.
