Mainframe JCL is powerful, but it’s also rigid, complex, and hard to learn. Jol was created to fix that.
Jol is a high‑level, English‑like language that replaces most of the complexity of JCL. It makes batch jobs easier to write, easier to understand, and far easier to maintain.
What Jol brings to the table:
Clean, readable commands instead of cryptic JCL syntax
Built‑in scheduling and job dependencies
Automatic dataset attribute handling (no more RECFM/LRECL coding)
Full scripting features: variables, logic, loops
Dataset operations like allocate, copy, sort, delete
Optional JCL generation for compatibility with existing workflows
In short, Jol modernizes mainframe operations by making them more accessible, more reliable, and dramatically easier to manage.
If your organization still relies on JCL, Jol is a powerful way to simplify and future‑proof your batch environment.
