That worked. Thank you very much for the reply. I am relieved.
I don't understand it though and I can't recall seeing it covered
anywhere. If anyone can share a reference or can explain why it
applies in the case of my ll example but not the case of (<'=') i.
('=';'=';'=.';'=.') that would be great
Here's the closest I came to understanding it:
From the wikipedia article on rank
Nouns, in J, are arrays. The rank of a noun is the number of
dimensions of that array. The derived verb #@$ determines the rank of
a noun.
Using that to look at each, I can see that they are different
]ll
┌─┬─┬──┬──┐
│=│=│=.│=.│
└─┴─┴──┴──┘
#@$ each ('=';'=';'=.';'=.')
┌─┬─┬─┬─┐
│0│0│1│1│
└─┴─┴─┴─┘
#@$ each ll
┌─┬─┬─┬─┐
│1│1│1│1│
└─┴─┴─┴─┘
