Hello, (Sorry for the previous empty email - web page problem)
please excuse another newbie question ... Ref: https://code.jsoftware.com/wiki/Vocabulary/starco pythag =: +&.*: 3 pythag 4 5 + operated dyadically and acted on both x and y - ok. but how does *: know to act on x as well? Isn't pythag using the monadic definition of *: to square y only? so magical ... thank you for the pointer and have a great weekend.
