Overview

Audio

This course describes how to define and work with the more complex data types that RPG supports. The course begins by describing how to define and work with variable-length data items. Run-time arrays are covered next. You will see how to define, initialize, modify, search, and sort a run-time array. The course then describes how to define and load two other types of arrays: compile-time and prerun-time arrays. This is followed by a discussion of RPG tables. You will see how to both define and work with tables. The course ends by describing multiple-occurrence data structures. You will see how to define a multiple-occurrence data structure and how to reference the data that it contains.

Approximate Study Time: 90 minutes
