TRENDS IN MODERN EXCEPTION HANDLING

Exception handling is nowadays a necessary cornponent of error proof Information systems. The paper presents overview of techni ues and models of exception handling, problems con- nected with them and potential Solutions. The aspects of implementation of propagation mechanisms and exception handling, their effect on semantics and genera program efhcJen- cy are also taken into account. Presented mechanisms were adopted to modern programming languages. Considering design area, formal methods and formal verihcation o f program pro- perties we can notice exception handling mechanisms are weakly present what makes a field for futur research
