I believe it's too late for 9.2 which is an old archived realease. I'll try to submit them for 10.11+ and do it the right way.

That's a game changer, thank you so much for this complete example! I'm very happy someone knowledgeable in MIT Scheme found this place. I did try to feed the correct string size to the functions, I tried padding with null bytes... but to no avail. I don't have a lot of free time these days and I plan to slap that new cool feature on SchemeBBS before everything else. Frankly, had I known before, I would have implemented tripcodes in Scheme. I might stick with MIT Scheme for further devlopments, if I manage to port SchemeBBS to v10.
I also need to get rid of the buggy irregex.scm. With Anon's invaluable help we found a workaround and that's another bug which wasn't brought to the attention of the maintainer (Alex Shinn), even though Anon thoroughly dug into it. I didn't plan to use the irregex dependency at the beginning. The specs specifically stated "no regex for the parser, no regex anywhere" but I had to finish the project before I found myself in no position to work on it anymore and regexes were the fast lane for some part of the markup line parser.
