Modernizing Your File I/O with Data Structures

Using Data Structures with I/O operations has been around for a while now. Our friends at Rational continue to build more and more functionality around using Data Structures for I/O because of the restrictions that it eliminates. In this session, we will dive into the various enhancements to database I/O made possible with the use of Data Structures. 

Learning Objectives:

  • Discuss general advantages of using Data Structures for I/O operations
  • Take a look at examples of various I/O opcodes using Data Structures
  • Discuss using Data Structures to handle program described files
  • Discuss %KDS built-in function and LIKEREC(*KEY) keyword
  • Explain local file support in i 6.1 and how Data Structures are used
  • Discuss new feature to allow long field names in i 7.1
