Example output
I'll help you optimize the COBOL code and provide insights. Let me break this down step by step:
### Condition Check
I notice that `cddt` (the target language) is not specified, so I'll first optimize the existing COBOL code following best practices.
### Code Optimization for COBOL

### Optimization Highlights:
1. **Improved Naming Convention**:
- Used meaningful prefixes like `WS-` for working storage
- More descriptive variable names
- Consistent naming across variables
2. **Modular Structure**:
- Separated initialization, input processing, and termination into distinct paragraphs
- Created clear, single-responsibility paragraphs
- Improved readability and maintainability
3. **Enhanced Error Handling**:
- More descriptive error messages
- Consistent error status checking
4. **Buffer Management**:
- Added a maximum buffer size variable
- Improved input retrieval logic
- Predefined input buffer with clear initialization
5. **Control Flow**:
- Main processing loop with clear termination condition
- Explicit initialization and termination sections
### Conversion Note
Since no specific target language was provided in `cddt`, I cannot perform a language conversion. If you'd like conversion to a specific language, please specify the target language, and I'll help you translate the optimized COBOL code accordingly.
Would you like me to elaborate on any part of the optimization or clarify the conversion requirements?
