Here <@(...) has a fork so
<@(_4: {.!.'0' ":) b. 0
_ _ _
<@(_4: {.!.'0' ":)"0 b. 0 NB. needs fixing with "0
0 0 0
Otherwise
<@(_4: {.!.'0' ":) i.10

| 8 9|

Another way is to use "each" or "every":
pad=: {.!.'0' ":
_3 pad each 1 10 100
+---+---+---+
|001|010|100|
+---+---+---+
10 {.!.'.' every ;:'a one three'
a.........
one.......
three.....

There's that rank 0 again!
I know that its discussed in the books but can anybody give a simplistic
explanation on why and when to use rank 0? I only use rank 1 and its
most likely I misunderstand it. I only use rank 1 when I try to apply a
verb on the column level of a two dimension matrix. I assume (from what
I've read so far) that rank zero is the rows of a two dimension matrix
and is assumed that its there and is omitted.
So why rank 0 again?
Thanks.

As a retarted J4.05 user lacking 8!:2 I'd do this:
<@(_4: {.!.'0' ":)"0 i. 10
