Introduction

This glossary defines many of the terms used in this book. It includes 
terms and definitions from the IBM Dictionary of Computing, as well as 
terms specific to the Presentation Manager, but it is not a complete 
glossary for OS/2. 

Other primary sources for these definitions are: 

   *  The American National Standard Dictionary for Information Systems, 
      ANSI X3.172-1990, copyrighted 1990 by the American National 
      Standards Institute, 11 West 42nd Street, New York, New York 10036. 
      These definitions are identified by the symbol (A) after the 
      definition. 

   *  The Information Technology Vocabulary, developed by Subcommittee 1, 
      Joint Technical Committee 1, of the International Organization for 
      Standardization and the International Electrotechnical Commission 
      (ISO/IEC JTC1/SC1). Definitions of published parts of this 
      vocabulary are identified by the symbol (I) after the definition; 
      definitions taken from draft international standards, committee 
      drafts, and working papers being developed by ISO/IEC JTC1/SC1 are 
      identified by the symbol (T) after the definition, indicating that 
      final agreement has not yet been reached among the participating 
      National Bodies of SC1.
