Örnekler

Bu örnekte ve CursorTop özellikleri ile SetCursorPosition ve Clear yöntemleri gösterilmektedirCursorLeft. Örnek, "+", "|" ve "-" dizelerinin birleşimini kullanarak 5 karakterden 5 karakterlik bir dikdörtgen çizmek için sonraki yazma işleminin nerede gerçekleşeceğini belirleyen imleci konumlandırıyor. Dikdörtgenin diğer dizelerin bir birleşimini kullanarak daha az adım ile çizilebileceğini unutmayın.
