Mastering COBOL
註釋The book uses hands-on examples and extensive coding samples to teach the reader how to enhance their Cobol skills. It covers the key issues facing today's Cobol programmer, such as Legacy Code updates, Year 2000 corrections, Euro conversions, Web migration and more. The book begins with a language refresher and reference and then guides the reader into the depths of legacy code, building a tutorial using actual legacy code as the foundation. It explores the year 2000 problem in depth, both as a guide to the programmer tasked with fixing this problem, and as an example of responsible modification of existing code. It describes structured COBOL programming and examines the key issues behind moving existing COBOL code into the 21st century with migration and integration strategies.
