OK, checkpoint E for the J Primer suggests that we play around with some verbs
other than "+" and so I got this out of "," -
(i. 2 3) , 7
0 1 2
3 4 5
7 7 7
I applied my dyadic verb processing worksheet to this, but ran into problems
when I attempted bringing the arguments to a common rank (of at least 1) by
repeatedly itemizing (,:) any of lower rank per
http://www.jsoftware.com/help/dictionary/d320.htm
Write out the entire expression: (i.2 3) , 7
Write out the abbreviated verb rank: _ _ _
Expand the verb rank(*1): _ _ _
Rank Calculation:
----------------
left-noun-rank: 2 right-noun-rank: 0
left-verb-rank: _ right-verb-rank: _
lesser left rank, lr = 2 lesser right rank, rr = 0
The verb will be applied to 2-cells of the left operand
and to 0-cells of the right operand.
left-noun-shape: 2 3 right-noun-shape: empty list
Frame Calculation: per http://www.jsoftware.com/jwiki/Essays/A_Fine_Line
-----------------------------------------------------------------------
left-frame: lf = empty right-frame: rf = empty list
Result frame will be longer of the two frames, which is an empty list
Now, consult the dictionary -
x,y appends items of y to items of x after:
1. Reshaping an atomic argument to the shape of the items of the
other,
The items of i. 2 3 are of shape 3. So 7 becomes 3 $ 7 or 7 7 7
2. Bringing the arguments to a common rank (of at least 1) by
repeatedly itemizing (,:) any of lower rank, and
I cant figure out what expression is being used on 7 7 7 here... help
needed
3. Bringing them to a common shape by padding with fill elements
in the manner described in Section II B.
Not entirely sure about this either.
