....while preserving the semantics of the program such that at the specified point the variable produces the same value as its original program. Program slicing has been widely used in many software activities, such as software analyzing, understanding, debugging, testing, maintenance, and so on [2, 12, 19]. Slicing algorithm can be classed according to whether they only use static information (static slicing) or dynamic execution information for a specific program input (dynamic slicing) This paper focuses on the dynamic slicing methods. There have many dynamic slicing methods proposed in ....

.... of the sentences involved in a slice is accomplished automatically applying dependencies analysis on the data and control flows [18] This technique, that in principle has been applied to the programs understanding and debugging, has also been adapted to other contexts as maintenance [4] [7], 8] reuse [9] 10] programs specialization [15] analysis of software architecture [23] reProceedings of the Fifth European Conference on Software Maintenance and Reengineering (CSMR01) engineering systems OO [17] programs evaluation [2] etc. With the present work a new area of ....

....slice is analogous to the concept of program slice [18] Given a program and a set of variables, a program slice consists of all statements in the program that may a ect the value of the variables in the set at some given point. A slice could be static [18] or dynamic (for a speci c program input) [9]. The notion of a slice has been also extended to distributed programs [8] Program slicing has been shown to be useful in program debugging, testing, program understanding and software maintenance [9, 18] A slice can signi cantly narrow the size of the program to be analyzed, thereby making the ....

....In some applications static program slices contain superfluous instructions. This is the case for debugging, where we have dynamic information as well (the program has been executed) Therefore, debugging may require smaller slices, which improves the efficiency of the bug revealing process ( 2] [13]) The goal of the introduction of dynamic slices was to determine those statements more precisely that may contain program faults, assuming that the failure has been revealed for a given input. First, we briefly review the program representation called Program Dependence Graph (PDG) 9] The PDG ....
