The present invention relates to a method and a computer arrangement comprising a processor and a memory. The processor is operatively arranged to execute a group of instructions (program) present in the memory unit, so that said program can initiate execution of other programs, supplying said started programs with some data in memory in a standard format (environment), optionally used by said started programs and normally inherited by implicit copying or reference at further initiations of other programs. The invention provides extra inheritance paths for the environment data so that programs can be configured to inherit environment data from ancestor programs other than their immediate ancestors, overriding the environment of the immediate ancestors. This makes it possible to manage separately the behavior of application programs which start each other and would otherwise inherit the same environment. Selective inheritance is accomplished by ancestor processes putting specially formatted data into distinguished environment data objects (variables) and by arranging descendant programs to be started via starter programs, said starter programs interpreting said distinguished environment objects and making adjustments to the legacy environment data before starting the actual program (application).
