Can someone please explain why the second example below works but the first does
not work?
Thanks very much.

\bTD \recurselevel \eTD\eTR}
\eTABLE
\dorecurse{2}
{\recurselevel. \recurselevel\crlf}
\stoptext

Are you sure ? What is a normal user ? As soon as you use \dorecurse , you become a programmer .

OK, it's hard to write a fancy layout without defining your own header styles etc. without a definition but use then as many high level contructs (\framed, \define, ...) as possible and try to avoid things like \vbox or \expandafter.

This is my point of view : "use TeX to write a document" = "write a program in TeX programming language" TeX programming language is not like lua, python, c++ , java and so on; TeX programming language is like m4, ie a macro language. If you write a simple document (= a simple program) context high-level const.s will almost completly hide the programming aspect ; but it's impossible that context "high-level" cover *all* program; so sooner or later one will use lua(tex) expression (which can be a "natural" choice for most of programmer but can be slow) , or ContTeXt macro (which can be less slow but not so natural ) , or even TeX macro - primitive . >http://texblog.net/latex-archive/plaintex/expandafter/ hey, this is not a "moderate use of expandafter" as I intended ..

I can't understand the relation between \setvalue and the expandafter trick in the example on the webpage, setvalue hides the csname ... endcsname part but the example tries to avoid the \let\oldmacro\macro \def \macro{\oldmacro...} redefinition.

There really is only one beginners book on Lua :-) _Programming in Lua_, by Roberto Ierusalimschy, the Lua author. There are a few other books, mostly about "Lua and games", because Lua has become quite popular in the gamers' community, but Roberto's book is really excellent and makes a good tutorial. > For example, one of the lines in the code is > > tprint = function(s) tex.sprint(tex.ctxcatcodes,s) end > > Is this Lua or LuaTex? The question does not really makes sense if you put it that way. This line of code is pure Lua, it is completely syntactically correct; but you can't use as it a standalone Lua script, because it uses functions that only LuaTeX and ConTeXt define (think of it as the action of "import" in Python, except that here it's not available as a stand-alone library call; it's built into LuaTeX). Hence, if you want to become proficient in Lua programming in ConTeXt, you need to learn: * The Lua programming language, with its core libraries (covered in the aforementioned book). * The Lua libraries that LuaTeX adds to Lua, documented in the LuaTeX manual. * The Lua libraries that ConTeXt adds to LuaTeX. The above line of code is really a mixture of the three, but in any case, the ground stone is always Lua.
