A method is disclosed to debug a computer program. The method provides a computer program comprising source code, and a listing of that source code. The method further provides a computing device comprising a data storage medium, and stores the computer program in that data storage medium. The method then runs the computer program, and subsequently detects an error condition. The method creates and saves to the data storage medium a dump file comprising (N) save areas. Using information abstracted from the dump file and the source code listing, the method reproduces the source code execution at the time the error condition was detected.
