Looks like I need to implement more security and error handling before I integrate the bλcode interpreter into a BBS.
Anyone has any suggestions for solving the halting problem?

Is it going to be a real implementation or just a bunch of random non-standard BBCode tags you post that don't actually do anything? Given this is /prog/, I'm inclined to think the latter.
