VAX COBOL On-Line: Interactive Programming Concepts and Examples
VAX is a family of computers from Digital Equipment Corporation ranging from PC's to mainframes. Provides users of VAX with an accessible source of information and demonstrates how to accomplish interactive (on-line) processing utilizing VAX COBOL. The essential logic building blocks of on-line inquiry, record add/change file access and on-line record deletion are fully explained along with more advanced features. A wealth of examples and illustrations aid users in exploring the interactive power of VAX and provide IBM-oriented personnel with the skills to branch out into VAX environments.
