Thanks, that helped me running the code and I saw I should have used loadstring instead of load.But then the second hurdle arises:function r(value, repeats)return string.format("value = %d repeats = %3d", value, repeats)endf = loadstring("r(3,4)")print ("f() = <“, f(), ”>")Alas, this returns: f = < nil >Clearly the call to r doesn’t has the result I had in mind.What is my error here?Hans van der Meer

Why is function r considered global and not found in the scope of function test(t)?Thanks in advanceHans van der Meer
