Hey Raul, I was speaking in context to the book 'arithmetic' not in general. In the exercises for the first chapter for example, it says to use two user defined verbs that the book has you define earlier in the chapter, but the problem is, is that you never do that ( i used the search function, not just scrolling up and down, there is no sign of these verbs). Another problem was that the following was a exercise and was asked by the book to write these out before computing it. i liked that idea. but the following never explained:
d =: 0 1 2 3 4 d >. d</d 0 1 1 1 1 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 d <. d</d 0 0 0 0 0 0 0 1 1 1 0 0 0 1 1 0 0 0 0 1 0 0 0 0 0 if >. is greater or equal to, why is 2's being printed across the chart? why with <., are true and false values being printed than the nouns in the vector like the >. shows? maybe the book really isn't for the level of novice i am, or the book just isn't laid out correctly. As i said i am reading the J primer and that has been much better so far. If i misread something in the 'arithmetic' book id like to be proven wrong. In regards to study time, ive been using most of my spare time learning to program as i find it fascinating, and it also doesn't cost me a dime (well, other than the hydro). regards, Joseph Turco The book On Sun, Sep 5, 2021 at 4:36 PM Raul Miller <rauldmil...@gmail.com> wrote: > You might also want to try some of the J labs. > > Also... my experience was that I needed to circle back and re-read > things after learning parts of the language.
