If I run the code below, which contains a viewmat and a plot when I run it
in JHS, I can copy the entire output into a Word document. Everything except
the plot appears correctly. Is there a way to capture the plot and insert

Very good point about verbal shorthands. The word "empty" is very likely to
trip up newcomers. Once they learn one meaning, they're less likely to look
out for others. Perhaps even experienced J'ers sometimes get tripped up?
Though they'll more easily work out the consequences of each possible

Empty arrays are perfectly clear. They are exactly those arrays with shape
containing at least one '0'.
I had not considered applying a verb with argument rank 'n' to a noun 'a'
of rank >:n where (>:n){$a is 0. Such an application has frame ,0. Applying
the verb to a noun of rank n is entirely dif
I think you meant your first sentence to be "It sounds like your
original confusion was between empty arguments (where the frame
contains 0) and a frame with an empty shape (which simply means that
the verb operates on a single cell)."
Empty shape is very different from empty of values.

Thanks Jose,
I have always admired your extreme tacit programming and wondered how you
do it. I can manage short tacits (about a line) but beyond that my stack
completely overflows.
Cheers

Well, perhaps you meant:

But

It sounds like your original confusion was between empty arguments
(where the frame contains 0) and an empty frame (which simply means that
the verb operates on a single cell).
