COBOL Snippet

IDENTIFICATION DIVISION. PROGRAM-ID. PAYROLL-SYSTEM. ...

Auto-generated Python

import decimal class PAYROLL_SYSTEM: class EMPLOYEERecord: def __init__(self): self.emp_id = 0 self.emp_name = "" self.emp_department = "" self.emp_salary = 0.0 self.emp_tax_rate = 0.0 def __init__(self): self.employee_file_path = 'employees.dat' ...

Ensure the input data file (employees.dat) exists in the same directory as the script.
