By the very same argument, the ASCII code table has syntax, since you can build Pascal, C, C++,... out of it. That's a red herring. TeX input has a lexical structure that is determined dynamically during the run, plus a macro language that doesn't have any syntax beyond the notion of (token,catcode) pairs. Not even brace tokens are proper syntactical elements, as the famous \ifnum0=`{\fi example shows. Over to Joachim Schrod..... Rainer
