MAC NAME:  J                                     

VERSION: 6.2                                 

README:
" J is a functional shareware programming language available via anonymous ftp at watserv1.waterloo.edu.
Features include list-at-a-time processing, arrays of arrays, complex numbers, special features for multiplying polynomials, manipulating sets and generating permutations.  Although it provides support for numerical modeling, it is not a numerical modeling package.  It is a general purpose programming language.
 J was designed and developed by Ken Iverson and Roger Hui. It is similar to the language APL, departing from APL in using using the ASCII alphabet exclusively, but employing a spelling scheme that retains the advantages of the special alphabet required by APL. It has added features and control structures that extend its power beyond standard APL."

I have a question about the language name:
What is the etymology of J (why this letter)?

   Roger Hui in his book "An Implementation of J" says that he selected it because it is easy to type.
