 CONTENT AND OBJECTIVES:
    1. Components of IMS DL/1
      • IMS component functionality.
    2. IMS DL/1 Structure
      • The architecture of an IMS database.
      • Segments/records, parent/child segments, and twins and siblings.
      • Segment limits and sensitivity, processing options, key sequence field, search field, DBDGEN, and PSBGEN.
    3. Program Structure and Interface to IMS
      • Calls to IMS and how they need to be coded.
      • Code a basic program which invokes IMS through DL/1.
    4. Database Retrieval Calls
      • Process the data in an IMS database using the GET call in DL/1.
      • Code WORKING-STORAGE, Linkage Section, and Entry Statement calls for retrieving input messages; these exercises utilize an existing database.
      • Perform GU, GHU, GN, and GNP operations.
    5. Database Update Calls
      • Update the data in an IMS database using the GET call in DL/1.
      • Using the database from the previous exercise, search for a segment, and perform a delete and replacement of values.
      • Insert new records into the database.
    6. Advanced Techniques
      • Code a complex search pattern.
      • Use the boolean operators to perform complex searches.
      • Code Qualified SSAs, Unqualified SSAs, and Boolean SSAs.
    7. Characteristics of a DL/1 Database
      • GSAM, HDAM, HIDAM.
      • How to reorganize a database.
      • Run the reorganize utility for the specified database.
    8. Logical Relationships and Searching
      • Add and use a secondary index.
      • Develop a query routine to a database from which the user can select a primary or secondary index.
    9. System Service Calls
      • The reasons for issuing Checkpoint Calls.
      • Issue a symbolic checkpoint.
      • Implement a PSB: Program Specific Block.
      • Recognize and appreciate the considerations associated with program and call parameters.
    10. Testing
      • Use DL/1 debugging aids for testing programs.
      • Issue a symbolic checkpoint.
      • Given a program with three errors, locate and fix the errors.
