I would like to thank Dr. Julio Gonzalez and Dr. Irene Dunne for their direction, assistance, and guidance. In particular, Dr. Gonzalez's recommendations and suggestions have been invaluable for the project and for software improvement. I also wish to thank Dr. James Michener, Dr. Esther Williams, and Mr. Edward Deming, who have all taught me techniques of programming and writing. Thanks are also due to Ms. Carol Morales, commuter specialist, Mr. Henry Chea, eligibility supervisor, and Mr. Hau Luu, tax consultant, for their assistance. Special thanks should be given to my student colleagues who helped me in many ways. Finally, words alone cannot express the thanks I owe to Don Smith, my husband, for his encouragement and assistance.
