If you are interested in the history of J, you might try seeing if anyone has a copy of ljdickey's watmath ftp archive. (J itself is significantly older than git, which in turn is significantly older than the J github archive. And, some parts of the language have been withdrawn. Also, while it doesn't address this particular question, I hope you have seen https://www.jsoftware.com/ioj/ioj.htm? Finally, although the page on "special code" -- https://www.jsoftware.com/help/dictionary/special.htm -- has become unlinked from some of the release notes, copies of those are on the jwiki (which also links back to older release notes which are still on the main site) -- https://code.jsoftware.com/wiki/System/ReleaseNotes -- and if you had looked through them, you might have spotted: https://www.jsoftware.com/docs/archive/release/error.htm which states: Errors that can never be signalled have been removed from the interpreter tables: defn error not reassignable result error I hope this helps.
