Employee Management Program

Overview

This COBOL program, EMPLOYEE-MANAGEMENT-PROGRAM, allows users to input employee data, store it in an external file, and then display a formatted table of employees with 10.5 or more years of service. It’s a simple demonstration of file I/O and data processing in COBOL.

Features

• Collects employee information interactively from the user:
  • Employee ID (6 digits)
  • Department Code (3 digits)
  • First Name (up to 20 characters)
  • Last Name (up to 20 characters)
  • Years of Service (e.g., 20.5)
• Writes the data to EMPLOYEE-FILE.txt.
• Reads the file and displays a formatted table of employees with 10.5+ years of service.
• Includes a header and separator line for the output table.

Prerequisites

• A COBOL compiler (e.g., GnuCOBOL or IBM Enterprise COBOL).
• A compatible environment to run COBOL programs (e.g., Linux, Windows with GnuCOBOL, or a mainframe).
• Write permissions in the parent directory for creating EMPLOYEE-FILE.txt.

File Structure

Output/Input File

• EMPLOYEE-FILE.txt
  • Format: Line-sequential
  • Record Structure:
    • Employee ID (6 digits)
    • Department Code (3 digits)
    • First Name (20 chars, alphabetic)
    • Last Name (20 chars, alphabetic)
    • Years of Service (3 digits, 2 before decimal, 1 after, e.g., 20.5)
  • Example:

    123456123John                 Smith                 015
    789123456Jane                 Doe                   012
    

Installation

1. Clone the repository:

   git clone https://github.com/ArmanBhatia0100/employee-management-program.git

2. Ensure the program has access to the parent directory (or adjust the file path in the FILE-CONTROL section).
3. Compile the COBOL program:

   cobc -x EMPLOYEE-MANAGEMENT-PROGRAM.cbl

Usage

1. Run the compiled program:

   ./EMPLOYEE-MANAGEMENT-PROGRAM

2. Follow the prompts to enter employee data:
   • Input each field as requested (e.g., Employee ID, Department Code, etc.).
   • Choose "Y" to continue adding employees or "N" to finish.
3. After input is complete, the program will display a table of employees with 10.5+ years of service.

Sample Interaction

WHAT IS THE EMPLOYEE-ID? ex(123456)
123456
WHAT IS DEP-CODE? ex(123)
123
WHAT IS THE FIRST NAME?
John
WHAT IS THE LAST NAME?
Smith
WHAT IS THE YEAR OF SERVICE? (ex: 20.5)
15.5
DO YOU WANT TO CONTINUE? Y/N
N

Output:

EMP-ID DEPT FIRST-NAME           LAST-NAME            SERVICE-YEAR
--------------------------------------------------------------------------------
123456 123  JohnSmith15.5

Program Structure

• IDENTIFICATION DIVISION: Defines the program name and metadata (author: Arman Bhatia, date: Feb 10, 2025).
• ENVIRONMENT DIVISION: Configures the employee file.
• DATA DIVISION: Defines file structure and working storage variables.
• PROCEDURE DIVISION: Main logic:
  • 101-INITIALIZE-OUTPUT-FILE: Opens the file for writing.
  • 102-GET-INPUT-FROM-USER: Collects and writes employee data.
  • 103-CLOSE-OUTPUT-FILE: Closes the output file.
  • 201-INITIALIZE-INPUT-FILE: Opens the file for reading.
  • 210-PRINT-HEADER: Displays the table header.
  • 202-GET-RECORD-FROM-FILE: Reads and displays qualifying records.
  • 203-CLOSE-INPUT-FILE: Closes the input file.

Limitations

• Displays only employees with 10.5+ years of service.
• No input validation (e.g., accepts invalid formats).
• Output formatting is basic and lacks consistent spacing.
• Overwrites EMPLOYEE-FILE.txt each run (no append mode).

Contributing

Feel free to fork this repository and submit pull requests for enhancements, such as:

• Adding input validation for numeric and alphabetic fields.
• Improving table formatting with better spacing.
• Supporting file append instead of overwrite.
• Including all employees in the output with a filter option.
