Help greatly appreciated. So unless I hear screaming and hollering, I'm using: If, due to the nature of C, there is no need for func2, then there is also no need to fetch the 2nd and 3rd arguments. For J. original: C言語の性質から使う必要がなければ第2、第3引数を受け取る必要はありません。 And thanks for the J. rewrite, Sugihara-san, that confirmed my quess. (Ch9 will be out of my hands soon within an hour. Ch5 is next.)
