Dynamic Debugging in BASIC

Dynamic Query-Based Debugging

Program errors are hard to find because of the cause-effect gap between the time when an error occurs and the time when the error becomes apparent to the programmer. Although debugging techniques such as conditional and data breakpoints help to find error causes in simple cases, they fail to effectively bridge the cause-effect gap in many situations. Dynamic query-based debuggers offer programm...

Application of Dynamic Slicing in Program Debugging

A dynamic program slice is an executable part of a program whose behavior is identical, for the same program input, to that of the original program with respect to a variable(s) of interest at some execution position. In the existing dynamic slicing tools dynamic slices are represented in a textual form, i.e., a dynamic slice is displayed to programmers in the form of highlighted statements or ...

Parallel Relative Debugging with Dynamic Data Structures

This paper discusses the use of “relative debugging” as a technique for locating errors in a program that has been ported or developed using evolutionary software engineering techniques. It works on the premise that it is possible to find errors by comparing the contents of key data structures at run time between a “working” version and the new code. Previously, our reference implementation of ...

Static and Dynamic Debugging of Modelica Models

The high abstraction level of equation-based objectoriented languages (EOO) such as Modelica has the drawback that programming and modeling errors are often hard to find. In this paper we present static and dynamic debugging methods for Modelica models and a debugger prototype that addresses several of those problems. The goal is an integrated debugging framework that combines classical debuggi...
