Re: http://www.jsoftware.com/help/primer/item.htm
Here is some suggested text for this section:
The items of a list are the atoms in the list. The items of a table are the rows
in the table. The items of a rank 3 array are the tables in the array. An array
is the list of its items.
Now, let's see some examples.
] table =. i. 2 3
0 1 2
3 4 5
] list =. i. 3
0 1 2
$ table
2 3
$ list
3
So the items of table with have shape 3. The items are 0 1 2 and 3 4 5
And list? Its items are atoms with shape 0. The items are 0 1 2
So basically, we can see the shape of items by simply lopping off the head of
the shape!
