      release = lv_release.
  
  WRITE: / 'SAP Release:', lv_release.
  
  " Check Unicode support
  CALL FUNCTION 'SYSTEM_GET_UNICODE'
    IMPORTING
      unicode = lv_unicode.
  
  IF lv_unicode = 'X'.
    WRITE: / 'Unicode: Supported'.
  ELSE.
    WRITE: / 'Unicode: Not supported - may cause issues'.
  ENDIF.
  
  " Check ABAP version
  DATA(lv_abap_release) = sy-saprl.
  WRITE: / 'ABAP Release:', lv_abap_release.
  
  " Recommendations based on release
  CASE lv_abap_release.
    WHEN '731' OR '740' OR '750' OR '751' OR '752' OR '753' OR '754' OR '755' OR '756' OR '757'.
      WRITE: / 'Recommendation: Use abapGit installation'.
    WHEN '702' OR '710' OR '711' OR '720' OR '730'.
      WRITE: / 'Recommendation: abapGit preferred, SAPLink as fallback'.
    WHEN OTHERS.
      WRITE: / 'Recommendation: Use SAPLink installation only'.
  ENDCASE.

Post-Installation Verification

After installation, verify system compatibility:

Run Demo Checker: Execute ZDEMO_EXCEL_CHECKER
Test Basic Functionality: Create simple Excel file
Check Version: docs/FAQ.md:5 - Verify VERSION attribute in ZCL_EXCEL class
Memory Test: Process sample data to check memory usage
