I'm rather new to J programming.
While reading the Primer, I've found that some of its pages seem not having
been completely updated from version 5 to version 6. For example, in the
Explicit-to-tacit page, one of the examples is:
fx =: 3 : '32 + y. * 9 % 5' NB. 3 explicit
ft =: 13 : '32 + y. * 9 % 5' NB. 13 tacit
Shouldn't y. have been replaced by mere y?
I also miss an introductory text to J programming, let's say a tutorial or
something similar.
Does somebody know a text on that line?
Thanks.
