You are saying that long-frame rationing doesn't happen sometimes.
What is the precise definition of long-frame rationing? Does this process ration the longer-frame noun into 0-cells always? If not, what determines what it is rationed into?
I say it always does. Let's try to resolve this. You give the example 2 3 4 5 4 3 -. 2 3 . But, as you have said, the frame for each operand is empty. (this is another way of saying that the verb is applied to its operands in their entirety). There is no frame that is longer than the other, so there is nothing to repeat. So long-frame rationing is performed, it just doesn't do anything.
Ok, just restating the above, with a bit more focus. Does J or the J verb decide how the rationing occurs? We see no mention of rationing in any J verb correct? It is a property of the J interpreter and described elsewhere?
Right? Some verbs can operate on operands of dissimilar shapes. , is an example. To find out what , does AFTER all the frame and replication stuff happens, you have to know what , does on its operands. You find that by reading the Dictionary.
Ok, I've added a step 3 under Operand Pairing here: http://hg.metaperl.com/j?f=d739eb121368;file=doc/dyad-proc.txt;style=raw Does the operand pairing section look sane to you now?
For verbs of infinite rank, like , and -. , the rules for agreement and replication end up by saying that the verb operates on each operand in toto. But that's not an exception to the rules - it's a consequence of the rules when the verb has infinite rank. There are no exceptions to these rules.
