Two resources occur to me. The first is probably closest to what you're
asking for:
http://www.jsoftware.com/jwiki/APL2JPhraseBook
credit to Ian Clark on that one. The second is a horse of a different
color:
http://rosettacode.org/wiki/J
Much like the Rosetta Stone helped people who knew Greek learn (ancient, and
lost) Egyptian hieroglyphics, RosettaCode can help people who know APL (or
C, Java, Basic....) learn J (or K, Lisp, Scheme, Haskell... ) .
In the short term, I think you'll find the first link the most helpful. In
the long term, the second. Because, of course, there is no one-to-one
mapping between APL and J. (Otherwise, there would be no reason for J.)

Subject: [Jprogramming] Need APL -> J cheat sheet
Greetings,
I know APL but I am having a lot of trouble finding the J operator or
sequence equivalent. If I could get to that point then I could
investigate J's new offerings one at a time. This would really give
me a jump start. I am aware of:
http://www.jsoftware.com/papers/j4apl.htm
It is a helpful overview. But what I need is a complete list of all
APL operators (in each of their functional aspects) to J equivalents.
This would considerably ramp me up on J. Is there such a thing? If
not, would someone be interested in helping me produce this?
Thanks.
Blake McBride
