Program development with SPARK

SPARK is an annotated subset of Ada for high-integrity programming. This subset, in conjunction with its system of annotations (formal comments), is designed to eliminate language ambiguities and insecurities, and to allow rigorous static code analysis and formal verification of programs. The development, flow analysis and correctness proof of SPARK programs is supported by a software tool, the SPARK Examiner. The paper outlines the essential features of SPARK and explains how the Examiner is used in program development.<
