Microsoft COBOL

Microsoft COBOL retains the high-level features of standard COBOL, and also introduces superior interactive capabilities and user-oriented features. Direct interaction between data, program and operator is possible. Compilation of COBOL source programs produces a compact object pseudo-code which is interpreted by the run-time system. The runtime system is a library of relocatable modules that are loaded selectively. Compilation speed is between 150 and 300 lines per minute. Special features include SCREEN SECTION for formatted screens, Program CHAINing for menu driven systems, Sequential/Line Sequential/Relative/Indexed Sequential files, Program segmentation, Trace style debugging, and COMP-3 Data Format. Accepts numbers of up to 18 digits and maintains accuracy of up to 30 digits during internal calculations.\n\nOriginal retail price: $700 (Westico Professional CP/M Software Catalog for ADAM, 1984)
