Full Description


This book does not aim to compete or fulfil the same role as introductory COBOL texts. Its main aim is to provide a tutorial on COBOL for experienced programmers who either need an update on the new standard or need to learn COBOL in addition to another programming language. Comparisons are drawn between COBOL and other languages, and a chapter is included on the significant differences between the old and new COBOL principally for those having to use a 1974 standard compiler or who need to maintain old programs written by other people. Assuming a grounding in one or more other programming language, the text provides a concise but reasonably comprehensive introduction to the language, and allows comparison of strengths and weaknesses of COBOL with other familiar languages.
