Jon,  I try to keep data and functions separate. Your example is about
specific funcgions and data.

(#:3)
1 1
   #:14
1 1 1 0
   
   (#:3),:#:14
1 1 0 0
1 1 1 0

g  is a constant with shape 4, so  g is "filled" to form the array.

Subject: [Jprogramming] Using ,: to prepend bits

This is a little problem I'm having.

Let
f =: #: 3
g =: #: 14

If I do f ,: g

I get

1 0 0 0
1 1 1 0

Here the shorter number , f, has a zero post-pended to match the shape of g.
I would like to find an equivalent verb that prepends the zero.
i.e. , in the case of the above f and g

f some_verb g
gives
0 1 0 0
1 1 1 0

Any help appreciated.

Jon
