Specification

<lsl> string NewLine(string message) {

   integer newlinepos = llSubStringIndex(message, "\\n");
   while(newlinepos >= 0)
   {
       message = llDeleteSubString(message, newlinepos, newlinepos + 1);
       message = llInsertString(message, newlinepos, "\n");
       newlinepos = llSubStringIndex(message, "\\n");
   }
   return message;

} </lsl>

A shorter alternative: <lsl> string NewLine(string message) {

   list lWords = llParseStringKeepNulls(message, ["\\n"], []);
   return llDumpList2String(lWords, "\n");

} </lsl>

   {
       message = llDeleteSubString(message, newlinepos, newlinepos + 1);
       message = llInsertString(message, newlinepos, "\n");
       newlinepos = llSubStringIndex(message, "\\n");
   }
   return message;
