// 01 — HOW IT WORKS
From dump noise to a fixable line of evidence.

        

          
01
Paste the dump
CEEDUMP, SYSUDUMP, or a job-log snippet, straight from your 3270 emulator or SDSF.

          
02
Decode the machine state
The engine decodes the PSW and registers, walks storage, and disassembles the exact failing z/Architecture instruction (FA3290D890D0 → AP D8(4,R9),D0(3,R9)).

          
03
Get the root cause
Plain-English root cause with the evidence quoted in hex (Operand 2 = X'F1F2F3' — zoned digits in a packed field) plus fix recommendations.

// 02 — EVIDENCE LOCKER
Built for shops where dumps are sensitive and change control is real.

        

          
[AIR-GAP]
Fully offline
Dumps never leave the machine. AbendLens is designed for air-gapped workstations and has no network code at all.

          
[STDLIB]
Zero dependencies
Pure Python standard library, nothing to install on z/OS, nothing to get past change control.

          
[INPUT]
Dump formats
Reads CEEDUMP, SYSUDUMP, and raw job-log snippets pasted from SDSF.

          
[Z/ARCH]
Disassembler
Decodes z/Architecture bytes, including AP D8(4,R9),D0(3,R9) from FA3290D890D0.

          
[PLAYBOOK]
Abend knowledge base
S0C7, S0C4, S0CB, U4038, and related cause-and-fix playbooks.

          
[JSON]
Automation output
--json output for pipelines, support dashboards, and repeatable triage.

// 04 — FAQ
Answers for the change-control meeting you do not need.

        

          
Does my dump ever leave the machine?
Never. AbendLens has no network code. Analysis is 100% local; it runs air-gapped. (This page itself makes zero external requests.)

          
Which dump formats are supported?
CEEDUMP, SYSUDUMP, and raw job-log snippets pasted from SDSF; JSON output via --json.

          
Do I need z/OS access or anything installed on the mainframe?
No. Nothing is installed on z/OS. You paste dump text into a tool on your own workstation; change control never has to hear about it.

          
How is this different from Abend-AID / Fault Analyzer?
Those are excellent site-licensed, quote-only products installed on the host — category licensing typically runs five to six figures per year. AbendLens is a workstation tool for shops that dropped that licensing: it covers the everyday "why did my batch job abend" workflow at a small fraction of any such renewal.
