Hi, There was some talk a while ago about the ambiguity of the dictionary about the direction of gerund insertion. Reading through the first pages of Iverson's Concrete Math Companion, I stumbled on a snippet of J that dates back to 2002 and was written by Iverson at the bottom of page 6: http://www.jsoftware.com/books/pdf/cmc.pdf According to this source, gerunds do indeed "unroll" from left to right correctly in the current implementation.
Cheers, Louis PS: sorry for my poor formatting, I'm on mobile. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
