You could've done it with ONLY one string.

pawn Code:

new str[1024]; // guess this is enough for a too long text
format(str, sizeof(str), "Long text"); // here str = "LongText"
format(str, sizeof(str), "%s Another long text", str); // here str = "Long text Another long text"
format(str, sizeof(str), "%s Last long text", str); // here str = "Long text Another long text Last long text"
