Adds three analytical reports for the Canada Day calculator programs in AS400/COBOL_examples/Holidays/QCBLLESRC.

Reports Added

  • cobol_analyzer_report.md - Code structure analysis covering data divisions, procedure flow, variable cross-references, and maintainability observations
  • cobol_dependency_report.md - Dependency mapping, modularity assessment (8.5/10 health score), data flow analysis, and refactoring recommendations
  • PRD.md - Language-agnostic product requirements document with functional specs, user stories, acceptance criteria, and implementation timeline

Programs Analyzed

  • CANDAY01.CBLLE - Interactive Canada Day calculator (161 LOC)
  • TESTCDAY.CBLLE - Automated test harness (48 LOC)

Key Findings

  • Zero circular dependencies; excellent modularity
  • Uses COBOL intrinsic date functions (INTEGER-OF-DATE, MOD)
  • Test program currently simulates testing; lacks LINKAGE SECTION for true integration
  • Supports year range 1600-3000 with input validation
