Hi again,
so I keep lugging away at trying to understand recognizers. I tried loading the rec-double-paren.frt example. However, even after adjusting the words from V3 to V4 it still falls over at the last line shown below. The terminal simply goes dead and I have to reflash the chip. Have I missed changing something? I have load all the dependencies and no errors up until that point occur. Kind regards Richard \ keep the previously active forth-recognizer stack variable old-f-rs wordlist constant comment-actions get-current comment-actions set-current \ only words in this wordlist are executed inside comments \ at least the )) is needed. \ switch back to the saved recognizer stack : )) old-f-rs @ to forth-recognizer ; immediate \ that's all for the comment actions set-current \ every word found is fine.
