Hopper

Hopper is a specialized development environment designed for mainframe systems, providing a modern interface for z/OS operations. Key capabilities include: * Integrated TN3270 terminal * Mainframe-aware panels for datasets, jobs, and spool output * Tools for inspecting datasets and editing PDS members * JCL generation and job submission * JES output parsing and failure explanation This platform streamlines mainframe development by consolidating essential tools into a single, intuitive application. Developers can write JCL, submit jobs, and debug mainframe workflows with greater speed and clarity. Its environment helps interpret complex JES output and offers assistance in understanding job failures. Hopper is ideal for mainframe developers and engineering teams seeking to modernize their z/OS development experience. It's built to accelerate traditional mainframe tasks, making debugging and operational processes more efficient across Windows, Linux, and macOS.
