Hello, what do I have to do so that the values (d1, m1, y1) from the Lua block are returned with Return and the commented out line \date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year] works in ConTeXt. In other words: how do I do it right? Thank you in advance Greetings Thomas PS. Sorry, I'm a totally novice in Lua. \starttext \startluacode function ddate(s) i = 1 j = 4 y1 = string.sub(s,i,j) i = 5 j = 6 m1 = string.sub(s,i,j) i = 7 j = 8 d1 = string.sub(s,i,j) context("Geht das: %s.%s.%s", d1, m1, y1) -- that works! --return d1, m1, y1 -- that works not! Why? end \stopluacode \def\DDate#1{\ctxlua{ddate("#1")}} \DDate{20241005} %\date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year] \blank \date[dd,mm,yyyy][weekday,{,~},day,{.~},month,{~},year] \blank \date[d=11,m=7,y=2024][weekday,{,~},day,{.~},month,{~},year] \stoptext
