True textual formats never use length codes, but indeed, many binary formats use scanning for delimiters (ASN.1 does this in some cases; a large object with lots of little ones can be sent with a length prefix, but if buffering it all isn't an option, it can be sent as a seqeuence of blocks with a special null block terminating it). There are myriads of ways of encoding things; categorising them depending on what subset of the values 0..255 they use strikes me as odd :-) What is perhaps really meant by textual is "layered on top of the local character set", which is a lot less of a fundamental distinction than might be imagined. > > Daniel > ABS -- Alaric B.
