Well, I think I got mislead on a quote by another user. I was looking
at line 139, which isn't actually the working code (#if 0 section).
Looking down at the correct lines (which you quote below) they are right.

Yeah, those I follow. Its also equiv to:

Tystream[j].size = ((buf[p] << 8) | (buf[p+1]) << 4) | (buf[p+2] >> 4);

which is what I've been using in tyc.
