J is a dialect of APL that has boxed arrays, complex numbers, user defined operators, and uses the ascii character set. It runs on several systems, and the code is intended to be easily portable from one system to another. Here is a little bit of code that might begin to show some of the similarites and some of the changes in J. stuff =. 'abcdABCD' $ stuff 8 stuff i. 'aA' 0 4 n =. i. $stuff sum =. +/ sum n 28 n sum n 0 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 2 3 4 5 6 7 8 9 3 4 5 6 7 8 9 10 4 5 6 7 8 9 10 11 5 6 7 8 9 10 11 12 6 7 8 9 10 11 12 13 7 8 9 10 11 12 13 14 i. 2 3 0 1 2 3 4 5
