Create a dependency reference markdown document for AS400/COBOL_examples/CallingExample/QCBLLESRC/

[raykao]

We need to analyze the code in the repo directory /AS400/COBOL_examples/CallingExample/QCBLLESRC/

As an expert COBOL dependency analyzer, analyze the provided COBOL code structure in the project directroy and identify:

1. Data flow dependencies between copybooks
2. Potential circular dependencies
3. Modularity recommendations
4. Legacy patterns that affect dependencies

Provide a brief analysis of the dependency structure and any recommendations. Once you have done that create a new Markdown document along side the program code as a reference document going forward.
