IBM i 5250 applications, originally designed for AS/400 systems, have been the backbone of business operations for decades. These text-based interfaces power critical processes in industries like manufacturing, finance, and logistics. However, their traditional desktop-bound nature limits flexibility in an increasingly mobile-driven world. Today’s workforce demands instant, anywhere access to enterprise applications on smartphones and tablets. Field employees, sales teams, and remote workers need real-time connectivity to legacy systems without being tied to outdated green screens.

As businesses strive for agility, modernizing 5250 applications for mobile use is no longer optional—it’s a necessity. Bringing these applications to mobile preserves the reliability of IBM i systems while meeting modern accessibility needs. Enabling mobile access, whether through web-based solutions, APIs, or UI enhancements, is a smart move for businesses to be more agile.

This is where aXes comes in. aXes provides a seamless solution for modernizing 5250 applications without modifying source code. It allows businesses to transform green screens into web and mobile-friendly interfaces, enabling users to interact with IBM i applications from any device.

Adapt Your Applications to Mobile with aXes

Successful transformation of 5250 applications involves enabling access on mobile devices and creating secure, optimized, and sustainable mobile experiences that drive efficiency and user satisfaction.

aXes is a no-code/low-code approach to modernizing your green screens and optimizing them for mobile.  It goes beyond simple UI refacing by enabling smooth integration of essential mobile features into your applications. With aXes, you can improve functionality by incorporating tools like camera-based document scanning, barcode reading for inventory management, and geolocation tracking for field operations. These capabilities allow your applications to adapt to modern mobile workflows to improve efficiency and usability.

By bridging the gap between traditional applications and mobile technology, aXes sees to it that your software is not only visually optimized but also fully equipped to handle real-world mobile tasks with ease.

Here’s a step-by-step guide to help you get started with this transformation:

  • Web-Enable and Transform Green Screens

aXes modernizes the user interface of legacy IBM i applications without touching its source code. It automatically converts IBM i 5250 screens into interactive HTML, eliminating the need for extensive redevelopment.

With aXes, developers can utilize a drag-and-drop editor that allows businesses to enhance applications with Google Material Design themes, mobile-friendly layouts, and interactive elements.

Green screen input fields can easily be replaced with touch-friendly controls and responsive layouts. Developers can also transform menus into clickable links, function keys into buttons, and subfiles into scrollable tables, all without coding.

  • Menus become clickable links – Instead of typing numbers or commands to navigate, users can just click on options, like in a regular website.
  • Function keys turn into buttons – Instead of pressing old-style function keys (like F3 to exit), users can just click a button.
  • Tables become scrollable – Instead of paging through data manually, users can scroll up and down like on a modern website.

By leveraging these capabilities, businesses can improve usability, boost efficiency, and extend the lifespan of their IBM i applications.

  • Enhance 5250 Applications with Mobile Features

aXes extends IBM i applications with built-in support for modern device functionalities. It allows 5250 applications to interact with mobile hardware features such as cameras, barcode scanners, and GPS, without requiring extensive redevelopment. Once web-enabled, aXes allows applications to access device APIs and developers can incorporate mobile-specific actions in the application’s UI with minimal coding. These capabilities allow businesses to enhance their IBM i applications to make them more adaptable, efficient, and user-friendly in mobile environments.

  • Test and Deploy

aXes simplifies the testing and deployment of your mobile applications. It provides an intuitive environment where you can quickly verify that the transformation applies flawlessly on various devices and screen sizes. With this, you can confidently deploy your application to empower your mobile workforce while bypassing the complexities of traditional methods.

  • Keep Modernized Applications Up-to-Date

aXes provides regular bug fixes, product updates, new features, and a dedicated support team. It also helps users stay up-to-date with the latest advancements in the mobile platform and access assistance, including improvements in UI/UX, performance enhancements, and new integrations as outlined in the application development roadmap.

From Legacy to Mobile: The Future of 5250 Applications
