thanks Robert!
OK. boxes are atoms withb an empty shape.
I've looked at the docs and can't see where I could read to understand why
shape of
1 2 +/ i. 4
is 2 1 and not 1 2

Hi Chris,
Well there is information on the vocabulary page for Table

also Nuvoc has good information on this verb

Hi
Could I work out from the docs that
< 1 2 +/ i. 4
┌───┐
│1 2 3 4│
│2 3 4 5│
└───┘
will give the above (2 1) shape result
and not a (1 2) result like below?
┌───┬───┐
│1 2 3 4│2 3 4 5│
└───┴───┘
With the (2,1) it's obvious that two 1-cells are returned,

try the following script, (untested)

create=: 3 : 0

)
bar_btn_button=: 3 : 0

is there a way to change syslocalep for a form? change it to a numbered
locale? in j803?
I am referring to syslocalep.
it would simplify having an object create its own form, and handling multiple
instances.
