<lsl> string j; j=llJsonGetValue(j,[]); //returns the whole "list" of a JSON. It might just be one entry or a whole nested list or whole nested object. //if "j" is a single JSON_STRING, this may return what the string represents as a JSON within a string; a JSON_NUMBER , JSON_TRUE ... j=llJsonGetValue(j,[1]); //returns only the first entry.
