A requirement of any source language is to be rich in features and concise to use by the programmers. As a drawback, it is often too complex to analyse, causing research studies to omit some of the fancy features. For instance, exception handling is an important aspect of programming languages that is instrumental for building robust software with good error handling capability. However, exceptions are often omitted during the initial formulation on program analysis and optimization. Moreover, when considering the traditional approach of converting programs from high level languages to machine code, the target code is meant for the machine, being too cryptic (or low level) for program analysis. Our goal is to design an intermediate, minimal but expressive, core calculus which can be easily analysed and manipulated, and to show that this calculus can handle major language features by translating a significant imperative source language into it. The translation to the core calculus enables us to easily analyse and optimize the code, while not sacrificing the flexibility and rich characteristic of the source language.

Exception handling is an important feature in modern programming methodology. However, it introduces abnormal control flows due to which the analysis becomes considerable more difficult. In general, automated verification of programs with diversified control flows can prove to be a difficult problem. We propose an approach to verification that handles different control flow types in a unified manner.
