Come on, Morris -- you've been participating here for this long, and you can't
guess the answer to that question -- you need someone to take the time to write
to you personally? Go to XyWWWeb; search (Ctrl-F) for "Stack" and "Ctrlchar".
When you find them, click on them. Make sure your power is switched on.

DeFaults and VAriables are the same thing.

Command "TABLE VARIABLES" (or "TABLE VAR") to see a complete
list that describes their meanings and values. Read your Customization Guide.

When all your windows are in use, WA WindowsAvailable isn't going to give you
any meaningful information, because no window is available. (Why in the world
do you want to populate all your available windows? You should always leave at
least one window unopened -- programs often need an available window, even you
might need one.)

Your surmise is correct: there is a reason. Look, you don't need _any_
VAriables to close all windows. In the simplest possible form, just issue
"AB/NV" repeatedly until you get an error:

BX ab/nvQ2 )>

This assumes that NW=1 or 3. You could always stick "BX rsQ2 " in the code
above, after the AB/NV procedure, to make sure the window is closed.
