All rights reserved.Next chapterContentsTeach Yourself COBOL in 21 days,Second EditionBy Mo BudlongDedicationI want to dedicate this book to the army of programmers and computer professionals who are alreadysweating or will shortly be sweating with the rest of us over the year 2000 problem.AcknowledgmentsIn this second edition ofTeach Yourself COBOL in 21 Days,I have had a chance to correct errors fromthe first edition, expand on areas that needed elaboration, and write about many of the new and excitingthings that are happening in the COBOL world. But most important to me, I have been able to act on thefeedback that I have had from readers of the first edition. All of it was good, and all of it was helpful.There are way too many of you to thank. There were lots of little suggestions and a couple of major ones,and they all have been incorporated. I want to thank you all.This is my third project for Sams and Macmillan, and I want to thank Chris Denny for noticing that thefirst edition was climbing the sales charts and for realizing that it was time for a new edition.I want to thank Heather Mlodinow, an accomplished COBOL programmer who reviewed the technicalend of the first edition, and Lee Ann Phillips who reviewed the second edition. Lee Ann was a tougheditor, but she was usually right, and I am particularly indebted to her for additional material on datesand calendars. Greg Adams, president of International Digital Scientific, Inc., also reviewed the dateschapters and provided helpful suggestions. All the Sams and Macmillan editors and crew have beenterrific. Ryan Rader, Rich Alvey, Drew Cupp, Heather Butler, Mary Ann Abramson, Fran Hatton, andGayle Johnson all gave excellent advice and encouragement.Mostly, I want to thank my wife Helen, who was not only my first line editor, but the first guinea pig totake the course. In fact, all three of the trial students--Helen, Victoria St. James, and ColleenLerian--were patient and capable and made it very easy to adjust the book to get it right for a newcomerto COBOL. The book is much better because of their efforts.In order to do this job properly, I needed to get my hands on a great deal of software and hardware, and Iwant to thank Micro Focus Inc. for providing Micro Focus Personal COBOL and Micro FocusProfessional COBOL, as well as a lot of encouragement.Acucobol Inc. graciously made its ACUCOBOL-85 package available.A huge team is involved in taking a manuscript from the author's pen (or word processor) to final print. Alot of help, advice, and changes are contributed by this team. But ultimately the book is the author'swork, and therefore I want to stress that I have made every effort to provide useful and accurateinformation, but any errors you find are mine alone.About the AuthorMo Budlonghas been a programmer and hardware engineer for 25 years.
