*** Birden fazla bileşen kullanarak tek bir bileşen oluşturma ***
Murat Turan

Aşağıdaki kodu boş bir üniteye yapıştırıp  MPSButon.pas adıyla kaydedip
delphiye tanıtın veya not defterine yapıştırıp MPSButon.pas ismiyle kaydedin.

Delphiye Nasıl Bileşen Kaydedebilirim?
1."Component" menüsünden "install Component..." komutuna tıklayın.
2.Karşınıza gelen pencereden "Browse..." (Unit file name karşısındaki) komutuna tıklayın
3.Dosyayı hangi konuma kaydettiyseniz o konumdan dosyayı açın (Unit file name karşısına dosya adı ve tam yolu gelecektir)
4.OK komutuna tıklayın
5.Karşınıza yeni gelen pencereden "Compile" komutuna tıklayıp kodu derleyin.
6.Bu işlem sonrası kontrol "Standard" bileşen sekmesine gelecektir.
