What is the best way to define the equivalent of \setvalue{\e!start\NAME}{...} in lua. e_start = ?? context.setvalue(e_start .. name, "...") Thanks, Aditya

This would just create \startfoo. \setvalue{\e!start foo} creates a interface specific command. The code that Hans posted does that. I am sorry that this was not clear in the question.

OK.
but the question is why don’t you use just tex to create the start/stop commands.
Because I find it much easier to understand expansion at lua level than at TeX level. Thanks, Aditya
