Product Overview
ALGOL is an applications and systems programming language. The ALGOL compiler includes provisions for interprogram communication, input/output (I/O) device handling, flexible data editing, and structured programming. In conjunction with other products, it provides facilities for structured programming, programmer productivity aids, and direct programming access to the Transaction Server and the MultiLingual System (MLS).
General Features
ALGOL is based on, and has all of the features of, ALGOL60—including structured control flow constructs, extensive arithmetic and Boolean expressions, plus nested procedure definition. Unisys Extended ALGOL adds other constructs and data types to simplify program writing and to enable programs to use some of the unique features of the enterprise server processors and operating system. These additional constructs are divided into five major categories.
