I'm really out of practice with J, and the meager-to-nonexistent documentation is not helping me. I have a very simple task to perform. I have a text file infile.txt on my desktop and here's what I want to do:
(1) read the file as lines (so I don't get all the end-of-line symbols); (2) sort the file's lines (alphabetically) (3) write out the result as a new text file, say outfile.txt, also on my desktop. I can do this trivially in Mathematica: t = Import["~/Desktop/infile.txt", "Lines"] Export["~/Desktop/outfile.txt", Sort[t]] But how would I do this in J (which, for longer files, ought to be faster) and how would I discover how to do it? I prefer to use named library functions where applicable. I tried the following in J801, after looking into text.ijs from J602: load 'files' t=. fread '~/Desktop/infile.txt load 'text' cuttext t | value error: cuttext What happened there?
