me!? some SQL related examples - monad ~. is like 'select distinct' - /. is like 'group by' - = etc. like 'where' - /: like 'order by' put it all together using one-array-per-column table example. select year,min(open),max(open),max(open)-min(open) from quotes group by year order by (max(open)-min(open))/min(open) skim over " and show how you can sum an entire matrix or sum each row. these sorts of things are what i expected to see when learning j... i knew j had powerful 'array at a time' ops, but i got bogged down in the labs and docs with little details -- i mean, i don't want to hear about k-cells and frames when i *know* i can get a handle on the language without having to know this detail. i first got interested in APL with arthur's kdb (which blew my mind -- it is still the most amazing piece of software i've ever come across) and that was in 2000. i've wanted to learn j/k ever since then, and it's only in the past month that i've written my first useful program. i've tried a few times to get into j with JforC, the primer and the labs. it could just be me, but i think it's hard to get into APL and the reason for me was the lack of "programmer related" examples. i'm happy to elaborate, or contribute to such doc if anyone is interested. ta, jack ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
