That may be true in theory Peter, but I am working on some code *now* that
requires an env var or two.  And since I currently have to roll my own fn()
(since it was not provided by CBM in 1.3), I would like to know whether I'll
need to change it under 2.0.  Eventually (read: when the 2.0 Native Developer
Package, or whatever is available), I'll change the code to use the official
library call, assuming there is one in this release, but it'd be nice to know
ahead of time if there will be problems due to a change in the implementation.

So I ask again, will the 2.0 implementation be of the "files" variety, or will
env: be a real device (as your "BTW" below would seem to imply)?

Sounds like a very useful enhancement.  How's this accomplished?

Thanks ...!
