COMMON POWERUp 2026

Arrays are a powerful but often underutilized feature in modern RPG. This session explores how free-format RPG makes declaring, initializing, and manipulating arrays easier, more efficient, and more readable than ever before. Attendees will see practical examples of dynamic arrays, built-in functions, and real-world scenarios where arrays improve program performance and clarity. From batch calculations to temporary data storage, this session provides actionable techniques RPG developers can apply immediately to modernize existing applications and write cleaner, more efficient code.

Learning Objectives:

By the end of this session, attendees will be able to: - Understand modern RPG array syntax and features. - Declare, initialize, and manipulate both static and dynamic arrays. - Apply arrays effectively in real-world RPG programs for improved performance. - Use built-in array functions like %LOOKUP, %SUBARR, and %SORT.
