This expression produces an error because b is a two-element vector and
a is a four-element vector, and are of incompatible lengths for ,¨ .
When you specified the elements of a, you enclosed each element in
parens which works only when there are two or more elements. When you specified b as in b←(0 0), the parens don't enclose the value. Perhaps
what you meant is to use the enclose function explicitly as in b←⊂0 0. Now

b,¨a ┌4──────────────────────────────────────────┐
│┌4───────┐ ┌4───────┐ ┌4───────┐ ┌4───────┐│
││ 0 0 1 2│ │ 0 0 2 3│ │ 0 0 4 5│ │ 0 0 6 7││ │└~───────┘ └~───────┘ └~───────┘ └~───────┘2

In this case, the scalar left argument to ,¨ extends to catenate the
scalar to each element in the right arg, as in

The most recent beta version of NARS2000.org supports )BOX ON to produce
the boxed displays seen above.

BTW, if you set your email client to encode the text as UTF-8, then you
can copy text directly from your APL program into an email msg, as I did
above.

yes i know that

above is wrong i did not know that, i would think the speech was for
fmt

so ok )BOX ON is fmt for all input

enclose for me means that operator depth here {equalunderbar} return
great than 0

{equalunderbar}1 2{cr}{lf}

{equalunderbar}1{cr}{lf}
0{cr}{lf}

Perhaps

That's correct, except for simple scalars where the depth remains at 0.
