The treatment of abnormal conditions in program design and coding raises several difficulties in the implementation of "good" programs. The scheme is of the controlled top-down kind: in the first step the normal program flow is analyzed; in the second step all the exception conditions are individuated and propagated from the lower level units to the higher level ones; in the third phase the exception conditions are raised in the program flow and treated in exception handler blocks. An example illustrates the methodological scheme.
