Tom,
I'm not quite clear on the practical steps involved in using this thing:
You write and load your data model.
Then you define your data model all over again using the query writer admin UI (plus some more stuff you define there).
Then /qw/qw.tcl will immediately start doing the right thing (thanks to nsv_arrays being set).
Is that it?
How do we know/ensure where the /qw/qw.tcl file is mounted?
