Legendary Mainframes Resurrected by AI? Introducing ‘Hopper’ that Automates COBOL Development!
📰 News Overview
- Hypercubic has released “Hopper,” the world’s first agent-based development environment for mainframes. It allows AI to perform operations within z/OS from a modern environment.
- The AI agent takes care of TN3270 navigation, querying VSAM, scripting JCL (Job Control Language), and debugging jobs.
- A free plan is provided for hobbyists, along with credentials to connect to Hypercubic’s mainframe for a free trial.
💡 Key Points
- One Prompt to Rule Them All: From compilation and testing to NEWCOPY (refreshing updates) for CICS, you can automate an entire workflow with just one command.
- Advanced Analysis and Debugging: Simply using
@-tag, the AI can instantly analyze JESMSGLG and SYSUDUMP. It identifies the source line causing an abnormal termination (ABEND) and finishes what would typically take hours of investigation in a flash. - Seamless Integration: Fully supports TN3270 terminal functionality, allowing secure connections to existing mainframe environments from macOS, Windows, and Linux.
🦈 Shark’s Eye (Curator’s Perspective)
Finally, the pinnacle of legacy technology—the mainframe—has been met with the fangs of cutting-edge AI agents! Up until now, developing on mainframes required the “artisan skills” of banging away at a black screen (TN3270) and painstakingly handwriting complex JCL. Hopper completely automates this process, allowing engineers to analyze SDSF logs with a single @-tag, which is an incredible relief! Instead of a “replacement,” the approach of layering a “new interface” of AI agents over the current z/OS to modernize it is exceptionally rational!
🚀 What’s Next?
The previously daunting barriers to mainframe operations are dramatically lowered, enabling younger engineers to maintain and expand legacy assets. The modernization of COBOL assets is likely to accelerate rapidly through AI agents.
💬 A Word from HaruSame
Riding the waves of AI on these behemoth machines is just too cool! I’m going to have AI write my JCL and spend my extra time gnawing on some jerky! 🦈🔥
📚 Terminology Explained
-
JCL (Job Control Language): A language used to define the execution order and resources for programs on mainframes, characterized by its strict formatting.
-
TN3270: A standard terminal protocol (and its screen) for communication with mainframes, requiring special operations distinct from modern GUIs.
-
CICS (Customer Information Control System): A general transaction monitor used to support large-scale online processing (like bank counter operations) on mainframes.
