Hi,
Thanks again for this detailed response. I favor free software and I use GNU/Linux. I also live in Emacs and I find the GNU APL mode very nice. So I think that with those and GNU APL I have good tools ;) I can get easy access to the 2 following books: - APL With a Mathematical Accent (C. A. Reiter) - APL\360 AN INTERACTIVE APPROACH (Leonard Gilman, Allen Rose) And I also have the pdf for Mastering Dyalog APL from the link you posted. So I think I am all set. I just need to start working on those. My goal is to widen my horizons beyond OOP and FP to become a better programmer. And also to have fun, of course. Thanks again to everyone who answered to my questions. You are a very welcoming community. Cheers. G.
