Popkin uses a step-by-step intuitive approach to teaching COBOL, which builds gradually to the presentation of advanced topics and complex programs. Students learn COBOL programming in a logical fashion. Many complete programs are given as examples to show students programming techniques in context. Comprehensive coverage of the COBOL language and extensions for interactive COBOL (Chapters 20 and 21) gives instructors flexibility in selecting course topics. Popkins clear writing style is easy to understand.Topic presentation flows logically, and technical terminology is well introduced and precisely explained. Students learn the correct terminology from the start. Applications are well suited to the concepts presented in each chapter, and provide realistic and up-to-date illustrations of COBOL use in business. Popkins applications are thorough, including full descriptions of files, realistic sample input and output, and error handling. Students gain a solid understanding of the COBOL programming techniques they will use in practice.
