BTW, I've seen real-world apps use SALC (e.g. something by Tomasz of FASM), also known as SETALC. But yeah, it's rare. There's some trick to emulate it, something like SBB AL,AL. (EDIT: corrected, I hope!)

INT3 isn't supported in JWasm, but INT 3 works fine (and produces 0xCC, not 0xCD 0x03 in case you were wondering). Guess even Japheth doesn't know everything.
