Hello, I encountered a weird error. The following code prints correctly to the console: ---- \starttext \startluacode print("\n@T") \stopluacode Abc \stoptext ---- Gives correct: " ... fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded @T backend > xmp > using file 'c:/ConTeXt/tex/texmf-context/tex/context/base/lpdf-pdx.xml' ... " But the following code fails (?!): ---- \starttext \startluacode print("\nT") \stopluacode Abc \stoptext ---- With: " ... fonts > fallback modern rm 12pt is loaded ! Undefined control sequence. system > tex > error on line 4 in file D:/Lukas/ConTeXt/Test/Env3/Test.mkiv: Undefined control sequence ... 1 \starttext 2 \startluacode 3 print("\nT") 4 >> \stopluacode 5 6 Abc 7 \stoptext 8 print("\nT ") \luat_start_lua_code_indeed ...tlua \zerocount {#1 }} l.4 \stopluacode ... " Any explanation? TIA. Best regards, Lukas
