Code: FUNCTION "f_UpperCase" : Void { S7_Optimized_Access := 'FALSE' } VERSION : 0.1 VAR_IN_OUT Text : String; END_VAR VAR_TEMP Quelle : String[100]; QuelleArray AT Quelle : Array[-1..100] of Byte; I : Int; END_VAR BEGIN #Quelle := #Text; FOR #I := 1 TO BYTE_TO_INT(#QuelleArray[0]) DO IF BYTE_TO_INT(#QuelleArray[#I]) > 96 AND BYTE_TO_INT(#QuelleArray[#I]) < 123 THEN #QuelleArray[#I] := #QuelleArray[#I] AND 16#DF; ELSIF BYTE_TO_INT(#QuelleArray[#I]) > 223 AND BYTE_TO_INT(#QuelleArray[#I]) <> 247 AND BYTE_TO_INT(#QuelleArray[#I]) <> 255 THEN #QuelleArray[#I] := #QuelleArray[#I] AND 16#DF; ELSE #QuelleArray[#I] := #QuelleArray[#I]; END_IF; END_FOR; #Text := #Quelle; END_FUNCTION Good luck!

So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

I also made a FB that uppercase the first letter (just do a FOR loop to uppercase every characters) // split into a char array Strg_TO_Chars(Strg:=#Text, pChars:=0, Cnt=>#length, Chars:=#"Array char"); // Convert the first char in int (ascii) #"Valeur ascii":= CHAR_TO_INT(#"Array char"[0]); //Compare to know if it's Uppercase or Lowercase (UPPERCASE = LOWERCASE - 32) IF #"Valeur ascii" > 95 THEN #"Valeur ascii" := #"Valeur ascii" - 32; END_IF; // Regenerat the string againe #"Array char"[0] := INT_TO_CHAR(#"Valeur ascii"); Chars_TO_Strg(Chars:=#"Array char", pChars:=0, Cnt:=#length, Strg=>#UPPERCASE);
