I have found this wiki:

But since I do not know Lua, I would appreciate that someone=
 gets me
started with my example.
Joas,

Perhaps there some confusion here about how ConTeXt is used to create a document, and what role Lua plays in it. ConTeXt is a macro-based language that provides a level of abstraction over TeX, which is also a macro language. Documents can be completely specified with the use of ConTeXt. Lua is a traditional programming language that is used by some versions of ConTeXt to optimize and extend some of the internal capabilities of ConTeXt and TeX. There are very few situations, if any, in which a document writer must resort to using Lua; ConTeXt almost always suffices.

Only the first example you found in the ConTeXt wiki uses Lua, and that example is not really useful for your problem. The other examples on that page are coded in the ConTeXt macro language.

You might also look at=C2=A0http://wiki.contextgarden.net/Syst= em_Macros/Handling_Arguments and http://wiki.contextgarden.net/Comm= ands_with_optional_arguments for more examples, and on the mailing list. I would also recommend looking in the mailing list for discussions of the \getrawparamet= ers and \getbufferdata and related commands (in particular=C2=A0= <= a class=3D"moz-txt-link-freetext" href=3D"http://www.mail-archive.com/ntg= -context%40ntg.nl/msg78808.html">http://www.mail-archive.com/ntg-context%= 40ntg.nl/msg78808.html).

Here is some code I use to format verse. It provides default values for the language, margin inset and continuation line indents that can be overridden when needed:

This type of code can easily be used to deal with the names, numbers, and abbreviations you describe in your requirements.
