The use of execution time diagnostics in pinpointing ambiguities in decision tables is discussed. It is pointed out that any attempt cit resolving ambiguities at compile time will, in general, be impossible. It is shown that, as a consequence, tree methods of converting decision tables to programs are inadequate in regard to ambiguity detection. Two algorithms for programming decision tables whose merits are simplicity of implementation and detection of ambiguities at execution time are presented. The first algorithm is for limited entry decision tables and clarifies the importance of proper coding of the information in the decision table. The second algorithm programs a mixed entry decision table directly without going through the inter- mediate step of conversion to a limited entry form, thereby resulting in storage economy. A comparison of the algorithms and others proposed in the literature is made. Some features of a decision table to FORTRAN IV translator for the IBM 7044 developed by the authors are given.

Observation that Nixon quotes himself 31 times directly, and innumerable times by reference to a previous statement; Tone of magisterial authority and imperial decisiveness; Concept of partnership; Evasive ambiguity of the Nixon Doctrine; Evasive ambiguity in the country's commitments.

The article presents a discussion on an adaptation of Euripides' "The Trojan Woman," by Sartre. The author reflects that the main differences between Euripides and Sartre's works lies in the use of words. He describes that Euripides writes in verses with ambiguity and sense of rhythm, while Sartre used direct statements as he is not a poet. He concludes that Sartre focused on a new core in his adaptation while retaining the external structure of the story.
