- ===============
-
- i think this is correct except that APL isn't really an applicative
- language and Ken Iverson agrees saying in a back issue of VECTOR that
- J incorporates those functional features lacking in APL.
-
- speaking ofwhich, i posted awhile back a translation of the "What is J?"
- tutorial by Lee Dickey into Mathematica showing how to do things like
- those mentioned above (rank, shape, depth) in Mathematica. If anyone has
- a copy of that could you send it to me. i lost the file in a near-fatal
- system crash. thanks.
