I'll be happy to give you a live personalised intro in https://apl.chat or head over to https://challenge.dyalog.com/ for an automated guided introduction (with a chance of winning a prize).

wow, thanks a lot! but my english is not good enough for a live "discussion" unfortunately :(

But maybe later, if you allow, I will contact you!

https://xpqz.github.io/learnapl/intro.html is a good place to start learning.

thanks for the link!
