The COBOL language needs little introduction. Created over 30 years ago for batch data processing, COBOL has withstood major changes in hardware capabilities, new applications and new programming ideas. It remains the most widely used commercial application language with no successor. This book is concerned with language skills and language understanding rather than programming methodology. No mention is made of testing, and no attention given to the environment in which programs must be entered, or executed. It is assumed that a reader will be familiar with these matters.
