Learn about array in as400
In AS400 (IBM i), an array is a data structure that holds multiple values of the same type, stored in contiguous memory locations. Arrays in AS400 programming, particularly in RPG (Report Program Generator), are used to store and manipulate large sets of related data. Arrays help organize data efficiently, especially when working with batch processing or performing calculations on multiple records. With fixed or dynamic array sizes, they allow developers to access, modify, and retrieve data quickly. Understanding how to define, use, and manage arrays is crucial for effective AS400 programming and optimized performance.
