Improve File Handling, STRING Formatting, and Error Logging

[tulu-g559]

Description:

This issue aims to enhance the payroll.cob program by improving file handling robustness, refining STRING formatting for better report readability, and adding error logging for better debugging.

Proposed Enhancements:

1. Improve File Handling:

   • Add FILE STATUS clauses to check for file opening and writing errors.
   • Display error messages if file operations fail.

2. Enhance STRING Formatting in Report Generation:

   • Use formatted display variables (e.g., WS-SALARY-DISPLAY, WS-TAX-DISPLAY) to ensure proper alignment of monetary values.

3. Better Error Handling & Logging:

   • Check FILE STATUS after OPEN and WRITE operations.
   • Print descriptive error messages when file operations fail.

Expected Outcome:

• Improved program stability by handling file-related errors.
• More readable payroll reports with correctly formatted salary, tax, and net pay values.
• Easier debugging through meaningful error logs.
