ASNA Mobile RPG is a mobile application suite for the IBM i. It enables RPG programmers to create smartphone and tablet applications with nothing but ILE RPG. Mobile RPG provides a screen design aid on which you drag and drop various UI elements onto the screens you're building. After creating the mobile displays they are exported to the IBM i as traditional display objects.
Mobile RPG's controls do most of the heavy lifting, moving data to and from the mobile display. They encapsulate traditional display file behaviors (eg reacting to function keys and indicator-driven conditional behaviors), transport data, and present data to the user. The gallery below shows Mobile RPG's controls and explains what they do.
