May we share some Rocket COBOL updates?

Hi everyone,

Welcome to Rocket® COBOL Fuel, your monthly source for all things COBOL. In this issue, you’ll learn about the GenAI-driven unit testing for COBOL applications, COBOL x JSON capabilities, and COBOL events.

 

Unlock Unit Testing for COBOL
with GenAI

 

You’re already testing applications today but as the pressure to deliver software faster and more frequently grows, unit testing becomes essential to ensuring quality long before code ever leaves the engineering team.

COBOL applications were not originally designed with unit testing in mind, making adoption challenging. GenAI changes that.  

This month, we’re excited to introduce AI‑driven unit testing for COBOL through a beta program and webinar. Watch the webinar to see the AI Unit Testing demo in action and join the beta to be among the first to try these new capabilities.

 

COBOL x JSON Demo

 

We’re excited to welcome you to the new episode of COBOL in Action, a new video series with short, hands-on, highly technical sessions with product demos. In this episode, we explore how you can use JSON with your COBOL applications. We invite you to share your questions, feedback, and topic ideas in the comments so we can shape future sessions around what matters most to you.

 

 

COBOL events

 

Thanks to everyone who joined our in-person events dedicated to COBOL modernization and networking in May. We hosted COBOL Days in Madrid, Sydney, Melbourne, and Brisbane this month. The event were full of real world success stories, product demos (including how GenAI can safely accelerate COBOL development), and best practices to evolve mission critical COBOL applications for the future. If you want a COBOL Day in your city, let us know in the comments.
