 \begin{lstlisting}[language=modelica]
 annotation(…, Text(string = "1st Frequency is %f1."), 
-                Text(string = "2nd Frequency "+"is "+String(f2)+".")…);
+                Text(string = "2nd Frequency "+"is "+String(f2)+"."), $\ldots$);
 \end{lstlisting}
 In this example only the string \lstinline!"1st Frequency is %f1."! can be translated, and no strings from the second line.
