Automated COBOL Code Generation for SNAP-I (Shipboard Nontactical ADP Program) CAI (Computer Aided Instruction) Development and Maintenance Procedures

摘要

In designing and implementing a computer aided instruction (CAI) prototype for the Navy Management System Support Office (NAVMASSO) as part of the Shipboard Nontactical ADP Program (SNAP), Data Systems Engineering Organization (DSEO) personnel developed techniques for automating the production of COBOL source code for CAI applications. This report discusses the techniques applied, which incorporate the use of a database management system (DBMS) to store, access, and manipulate the data necessary for producing COBOL source code automatically. The objective for developing the code generation techniques is to allow for the production of future applications in an efficient and reliable manner. This report covers the standards and conventions defined, database tables created, and the host language interface program used for generating COBOL source files. The approach is responsible for producing 85 percent of an 830,000 line COBOL application, in approximately one year's time. This code generation program generated transaction processing routines to be executed under the DM6TP NAVMASSO distributed processing environment on the Honeywell DPS-6 minicomputers, representing the standard SNAP-I environment.
