I always felt that Henry Rich's name for his book "J for C Programmers"
was a bit limiting, and potentially narrowed his audience too much.
Anyone interested in learning J should read Henry's book, not just C
programmers. It is a great educational and entertaining work, and has
helped me immensely in understanding the language (and I'm most
definitely not a C programmer).

Hi Terrence;
I've always thought that the frame and its shape were two different things.
I guess it is time to read {J4C} and see which one of us is indeed correct.
I'm not, nor ever will be a C programmer, thus I have not read it.

frame shape? that would be redundant.
the frame, is the shape of everything that is not the k-cell.
so for
q =: i. 4 5 6
the frame will be
4
4 5
4 5 6
depending on whether you have 2-cells, 1-cells, or 0-cells.
I think I'm right. Somebody put me in my place if I'm not :)

Hi Terrence;
Where on the page is the frame shape stated as 5 6. In my -:blindness I
don't see it.

<quote href = http://www.jsoftware.com/help/jforc/declarations.htm >
the frame, concatenated with the shape of the cells, will be equal to
the shape of the noun.
< / quote >
However, in the second given example, the frame is 5 6 the shape of
the cells is 4
Their concatenation is 5 6 4
But the shape of the noun is 4 5 6
Therefore the concatenation is equal to some permutation of the shape
of the noun but not necessarily equal to the shape of the noun.
