Interactive sandbox

Review a lending portfolio the way your analysts will.

This workbench holds a scan of LOANSYS: COBOL accrual and fee programs, the nightly JCL, and a PL/SQL posting package. Re-run the scan, trace rules to source, and sign them off.

What you just used

The review loop, not a chat window.

In a real engagement the same screens hold thousands of rules across hundreds of programs, with filters by program, kind, owner and status.

  1. 01Trace

    Select a rule and the exact source lines light up. Every rule PYD ENTERPRISES extracts carries a file and line range, so reviewers never take a description on trust.

  2. 02Decide

    Approve, flag or reject. Flagged rules are the interesting ones: the state cap table missing six states, the JCL COND that reads backwards, the 90-day non-accrual flip.

  3. 03Audit

    Every action lands in the audit log with actor and time, the same trail your model risk and internal audit teams receive with a real scan.

  4. 04Export

    Approved rules flow into the DMN 1.5 bundle. Anything still pending is listed separately, so nothing ships to the build team unreviewed.

Run this on your own code, inside your VPC.

The 14-day trial license covers up to 100,000 lines. Install with Helm, point it at a PDS export or a Git mirror, and review rules the next morning.
