Your Green Screen RPA Can Be Faster, Elegant, and Easy to Maintain

Yes, green screen automation can be made faster, cleaner, and easier to maintain by replacing terminal-session RPA with OL Screener, which exposes map-based CICS/BMS and IMS/MFS conversations as named-field ScreenFlow APIs without 3270/5250 terminal sessions or hand-authored terminal mappings.

How to modernize green screen RPA without adding more bots

Many organizations use RPA to automate repetitive green screen work. It often starts as a practical shortcut: automate the same screens users already know, without changing the core system.

But over time, screen-based automation can become difficult to maintain. When automation depends on terminal behavior, sessions, or hand-built mappings, even small process changes may create rework.

OL Screener offers a cleaner path: instead of driving a terminal session, it drives map-based conversation flows directly and exposes them as ScreenFlow APIs.

Why ScreenFlow APIs are easier to maintain than terminal automation

With OL Screener, screen interactions are represented through named fields rather than fragile terminal navigation logic.

That means integration teams can think in terms of business-relevant fields and flows, not just screen coordinates or manual terminal steps. The result is a more elegant approach to exposing green screen processes for applications, services, and modernization initiatives.

What changes

• Instead of automating a user interface session, you expose a reusable API flow.
• Instead of hand-authoring terminal mappings, you use map-based conversation flows.
• Instead of depending on 3270/5250 terminal sessions, you access the underlying screen flow without them.

What systems can OL Screener work with?

OL Screener is designed for map-based conversation flows, including:

• CICS/BMS via MQ
• IMS/MFS via IMS Connect
• Later AS400/DSPF support

This makes it especially relevant when the business process is still valuable, but the automation method needs to become cleaner and easier to maintain.

When to consider replacing green screen RPA

Consider OL Screener when your team wants to keep using proven mainframe processes, but reduce dependence on bot-driven terminal sessions.

Common reasons include:

• You want API-style access to existing screen flows.
• You want to avoid browser or terminal-session automation.
• You want named-field interactions instead of hand-authored terminal mappings.
• You need a more maintainable modernization path for CICS/BMS or IMS/MFS flows.

A practical modernization step, not a full rewrite

Modernization does not always require rewriting core applications. In many cases, the better first step is to expose the existing interaction as a cleaner interface.

OL Screener helps turn green screen conversations into ScreenFlow APIs, giving teams a faster, more elegant, and easier-to-maintain alternative to traditional green screen RPA.
