You’re right, Wolfgang, I chose the wrong sample. The next one (AFAIK) should work on every OS: \startluacode local user = "" local users = { ["ousia"] = 1, } function document.CheckUser() user = os.resultof("echo ousia") context.verbatim(user) end function document.UserNumber(name) context.verbatim(users[name or user] or 0) end \stopluacode \def\CheckUser {\ctxlua{document.CheckUser ()}} \def\UserNumber{\ctxlua{document.UserNumber()}} \starttext This is user \CheckUser with number \UserNumber. \stoptext >> Is there no way to do it with \processaction? > > Only when you ensure the text you get from Lua has the normal cathode > regime and when you special characters like \ in the result you have > to convert them to \letterbackslash etc. which isn’t simpler than > Hans solution.

Since this is a minimal part in a way more complex implementation (at least for me), I really need to use commands that I know what they do. Pure Lua code is totally unknown to me. I don’t have any background in programming. This is the reason why I asked about \processaction.
