Dear Hans, dear Mathieu, Thank you very much for your quick thoughts and solutions! It is amazing how fast one gets a solution to one's problem on this list… Just a note for Mathieu: I think that \enableregime[il1] is not needed in mkiv, since a unicode regime is the default there (however with mkii I use \enableregime[utf] but in the case we are discussing, one has to use lua, so mkiv is mandatory).

This following code works, except that the first random is always the same (Analysis) for some reason.
Anyone knows why ?
\enableregime[il1] \starttext \startluacode userdata = userdata or {} math.randomseed( os.time() ) function userdata.random(...) context(arg[math.random(1, #arg)]) end \stopluacode \def\CHOOSERANDOM#1{\ctxlua{userdata.random(#1)}} \dorecurse{10}{\CHOOSERANDOM{"Maths", "Physics", "Algebra", "Analysis", "Chemistry", "Geometry", "Wave equation", "Schrödinger equation"}\par} \stoptext

Hi all,
Assuming that we have a set of words or expressions, say {Maths, Physics, Algebra, Analysis, Chemistry, Geometry, Wave equation, Schrödinger equation} is it possible to write a lua function, named for instance randomselectword which returns one of the words or expressions selected at random in the above set? Indeed this is intended to be used in a TeX file processed with mkiv.
Thanks in advance for any idea and help.
