                 Dengan memanjatkan Puji Syukur kehadirat Allah, kami menyampaikan 
             tuntunan praktis Algoritma Pemrograman III ( Cobol ) ini kepada para pembaca yang 
             terhormat. Karena hanya dengan karuniaNya kami dapat menyelesaikan buku ini. 
                 Buku ini membahas langkah demi langkah bahasa pemrograman Cobol, 
             dengan disertai contoh-contoh untuk memberikan petunjuk dan kemudahan bagi 
             pembaca yang mempelajari Bahasa Cobol. Dengan dibuatnya buku ini,penulis 
             berharap bahwa pembuatan program aplikasi dengan bahasa Cobol tidaklah menjadi 
             sesuatu yang sulit. 
                 Tidak semua instruksi yang ada di Cobol dibahas dalam buku ini, hanya 
             instruksi yang erat hubungannya dengan pembuatan program aplikasi yang penulis 
             bahas. Instruksi-instruksi lain dapat dilihat dari beberapa buku acuan yang penulis 
             gunakan dalam penyusunan buku ini. 
                 Penyusunan buku ini dapat terlaksana berkat bantuan dari berbagai 
             pihak,antara lain Bapak Pimpinan Universitas Semarang yang telah memberi 
             kesempatan kepada Penulis. 
                 Dengan segala kerendahan hati,penulis menyadari bahwa buku ini masih jauh 
             dari sempurna, karena keterbatasan kemampuan pengalaman penulis. Karena itu 
             penulis ucapkan banyak Terima kasih atas saran dan kritik yang positif untuk 
             perbaikan serta penyempurnaan buku ini yang sangat penulis harapkan.
