How do I check in ConTeXt whether a control sequence is already defined (to avoid redefining it by accident)?
Marginally related to the above, I have tried to use \show, only to discover, to my surprise, that it gives an error. For example:
\show\NL \end
Does ConTeXt override some of TeX primitives?
yes, like \month ... but in general if you use uppercase or camelcase you're quite safe (there are some math symbols with uppercase but if you define your own commands you will probably not use those) ... mechanisms like tables that use \NC and so define them local
I see. Local commands are a good idea. I usually use camelcase, but since I wanted to define some two-letter sequences, I thought I'd better be cautious. Nicola
