One of the best books for learning COBOL is "Murach's Mainframe COBOL" by Mike Murach and Anne Prince. It offers a comprehensive approach to understanding COBOL programming, starting from basic concepts and progressing to advanced topics, all with clear explanations and practical examples. Another excellent choice is "COBOL for the 21st Century" by Nancy Stern, Robert A. Stern, and James P. Ley. This book provides a modern perspective on COBOL programming, covering important features like structured programming, modularization, and file processing. "Teach Yourself COBOL in 21 Days" by Mo Budlong is also a popular option for beginners, offering a step-by-step guide to learning COBOL programming in a relatively short timeframe. Each of these books caters to different learning styles and preferences, providing valuable resources for mastering COBOL programming.

COBOL stands for "COmmon Business-Oriented Language." COBOL was first introduced in 1959, and it is known for its readability and self-documenting code, making it suitable for applications that involve extensive input and output, such as data processing and business applications.It is a high-level programming language primarily designed for business, finance, and administrative systems.

Comprehensive COBOL Training and JCOBOL Online Coaching on UrbanPro
Introduction: As a seasoned tutor registered on UrbanPro.com, I specialize in providing top-notch COBOL training, including JCOBOL, through online coaching. In response to your query, I'll guide you on how to merge two files in COBOL, a fundamental skill in data processing.
Merging Files in COBOL: Step-by-Step Guide
1. Understand the Requirement: Before diving into the coding process, clearly define the merging requirements. Identify the key fields that will be used for merging, and understand the structure of both input files.
2. Sort Input Files: Merging in COBOL often requires sorted input files. Utilize COBOL-compatible sorting utilities or pre-sort the files using tools like SORT in JCL (Job Control Language) to ensure a seamless merge process.
3. Declare File Structures: In your COBOL program, declare the file structures for both input files using the FILE SECTION. Define the record layouts, including key fields that will be used for merging.
FD INPUT-FILE-1. 01 INPUT-RECORD-1. ... FD INPUT-FILE-2. 01 INPUT-RECORD-2. ... FD OUTPUT-FILE. 01 OUTPUT-RECORD. ...
4. Open Files: Use the OPEN statement to open the input and output files. Ensure that the file status is checked after each OPEN statement for any errors.
OPEN INPUT INPUT-FILE-1. OPEN INPUT INPUT-FILE-2. OPEN OUTPUT OUTPUT-FILE.
5. Read and Merge: Implement a loop to read records from both input files sequentially. Compare the key fields, and based on the comparison, write the merged record to the output file.
READ INPUT-FILE-1 AT END SET END-OF-FILE-1 TO TRUE END-READ. READ INPUT-FILE-2 AT END SET END-OF-FILE-2 TO TRUE END-READ. PERFORM UNTIL (END-OF-FILE-1 AND END-OF-FILE-2) IF KEY-FIELD-1 < KEY-FIELD-2 WRITE OUTPUT-RECORD FROM INPUT-RECORD-1 READ INPUT-FILE-1 ELSE WRITE OUTPUT-RECORD FROM INPUT-RECORD-2 READ INPUT-FILE-2 END-IF END-PERFORM.
6. Close Files: After completing the merge process, close all the files using the CLOSE statement.
CLOSE INPUT-FILE-1. CLOSE INPUT-FILE-2. CLOSE OUTPUT-FILE.
Conclusion: By following these steps, you can effectively merge two files in COBOL. If you are looking for the best online coaching for COBOL training, including JCOBOL, feel free to reach out for personalized guidance and comprehensive learning resources on UrbanPro.com.

Understanding the Evolution of COBOL and its Decline
COBOL (Common Business-Oriented Language) has been a stalwart programming language in the business and financial sectors for decades. However, several factors have contributed to its decline over the years.
While COBOL still exists in certain legacy systems, its decline is evident as businesses seek more agile, integrative, and cost-effective solutions. Transitioning to newer programming languages that align with contemporary technological trends is becoming imperative for staying competitive in today's dynamic IT landscape.
For individuals seeking to adapt to these changes, exploring alternative programming languages through online coaching, such as JCOBOL training, can be beneficial in staying relevant and competitive in the evolving job market. Online coaching platforms like UrbanPro.com offer a range of courses to help developers upskill and transition to more in-demand technologies.

In COBOL, the REDEFINES
clause allows you to define different data items that share the same memory space. It's used to create alternate views or interpretations of the same storage area, allowing multiple data items to refer to the same memory location.
When a REDEFINES
clause is used, it indicates that two or more data items occupy the same storage but interpret it differently based on their definitions. For instance, you might have a numeric field and a character field that both reference the same memory location, allowing you to access the data in different formats.
01 EMPLOYEE.
05 EMP-NAME PIC X(20).
05 EMP-SALARY PIC 9(6)V99.
01 EMPLOYEE-DETAILS REDEFINES EMPLOYEE.
05 EMPLOYEE-INFO PIC X(26).

COBOL gained popularity primarily due to historical factors rather than its inherent qualities. When it was developed in the late 1950s and early 1960s, it was one of the few high-level programming languages available. Its design focused on readability, allowing business professionals to understand and write code.
During the 1960s and 1970s, COBOL became widely adopted in government, finance, and large corporations. It was instrumental in building critical systems for these industries, handling essential functions like banking transactions, payroll processing, and inventory management. Its verbosity and English-like syntax made it accessible for non-programmers, enabling collaboration between business analysts and programmers.
However, over time, the perception of COBOL shifted. Its verbosity, rigid structure, and limitations in handling modern programming paradigms led to criticisms. As newer, more flexible languages emerged, COBOL became associated with outdated systems, and its popularity declined among newer generations of programmers.
