AS400 GUI modernization involves updating the graphical user interface (GUI) of IBM AS/400 (now IBM i) applications to align with contemporary design standards and user expectations. This process typically includes enhancing the visual appeal, usability, and functionality of legacy AS400 applications by implementing modern UI elements, improving navigation, and optimizing user workflows. The goal is to enhance user experience, productivity, and the overall competitiveness of AS400-based systems in today's digital landscape.
How Can AS400 GUI Modernization Help You?
Get past these challenges that you face in everyday workflows.
Manual Labor
Workflows are stuck in silos & often require manual intervention.
Limited Access
Users have a limited degree of freedom with the default AS400/iSeries features.
Low Productivity
The productivity of the in-house IT team dips, slowing the overall pace of the organization.
User Satisfaction
Working on green screens can bring down the happiness quotient by leaps & bounds.
Enterprises are hesitant to take a step as it requires replacing or rewriting systems, which incurs time, expense, and risk.

RPG Open Access allows programmers to access modern technologies within the existing RPG code by specifying programs that connect the modern tech to the RPG architecture. Open access (handler procedure) calls the existing program to complete I/O ops using tools.
RPG Open Access at a glance:
Developed by IBM
Get data from RPG
Uses existing RPG skillset
Bypasses 5250 data streams
Tools of trade
Pros:
- Quickest fix
- No load on 5250 data streams
- Minimal AS400 modernization effort
Cons:
- Underlying monolithic system
- Requires proprietary tools
- Requires coding for handler programs
This approach is focused to elevate the usability and flexibility of AS400 systems from the users’ perspective without tinkering with the underlying code.
Screen Re-facing at a glance:
‘Read n Write’ Data
Host HTML/CSS webpages
Quick turnaround time
No changes in the code
Tools of trade
Pros:
- Quick & easy to implement
- Multiple IDEs available
- Faster turnaround
Cons:
- Old HTML/CSS webpages
- Requires proprietary tools
- Underlying monolithic system
This method enables AS400 organizations to expose the features of their system as APIs to facilitate information exchange with internal and external systems.
Api & UI Framework at a glance:
Create new screens
Leverage REST APIs
Componentized
Future Ready Design
Tools of trade
Pros:
- Future-ready architecture
- Multi-vendor support
- Lightweight services & APIs
- AS400 modules used
Cons:
- Long-term project
- Requires proprietary tools
