# COBOL Sample Application

Sample mainframe application for testing JIRA AI Fixer.

## Structure

```
src/
├── cobol/
│   ├── AUTH.CBL      - Transaction authorization
│   ├── VALIDATE.CBL  - Input validation
│   ├── CLEARING.CBL  - Settlement processing
│   └── HOST.CBL      - Host communication
├── copybooks/
│   └── TRANSREC.cpy  - Transaction record layout
└── jcl/
    ├── AUTHPROC.jcl  - Authorization job
    └── CLEARJOB.jcl  - Clearing batch job
```

## Known Issues

For testing purposes, AUTH.CBL contains a deliberate bug:
- `WS-AVAILABLE-BALANCE` is defined as `PIC 9(9)V99`
- Should be `PIC 9(11)V99` to match HOST response
- Causes truncation on balances > $9,999,999.99
