A language system called the Automated Programmer automates a great deal of routine effort for scientific, engineering, and mathematical application programming. Its notation is modeled after conventional textbook mathematical representation, so that mathematical expressions can be entered just as they appear in conventional solution specifications. It uses a flexible vocabulary and syntax that emulates technical English. This approach enhances self-documentation, diminishes programming error, and eases maintainability and verifiability. System design is highly user-oriented, making the system easy to learn and use. Programs are input using a two-dimensional screen editor. Lexical restrictions are minimal, keyword synonyms are available, and various common synonymous syntactic structures are acceptable. Powerful input and output facilities are provided. >
