Book Summary of Cobol For The 21St Century Thoroughly revised and updated to reflect changes in the field, the eleventh edition of Structured COBOL Programming builds on the strengths of previous editions and includes changes and additions that have significantly improved the text. The dual emphasis on structured program design and syntax is retained, as is the focus on top-down modular programming and documentation. The text is intended for readers with no previous programming or computer experience as well as for those with some background in the computing field.
