COBOL Data Division: COBOL Data Division is used to define data structures such as variables, records, and files. It is important to measure this skill to ensure that the candidate can effectively work with data and understand the different datatypes and data manipulation techniques in COBOL.
COBOL Procedure Division: COBOL Procedure Division is where the actual program logic is written. It includes statements such as perform, if-else, and do-while, among others. Measuring this skill helps evaluate the candidate's ability to write efficient and logical program logic using COBOL.
File Handling: File handling in COBOL involves reading, writing, and manipulating files. It is crucial to assess this skill as it determines if the candidate can work with external data sources and perform operations like record-level processing and file organization in COBOL.
Sorting and Merging: Sorting and merging involve arranging data in a specific sequence and combining data from multiple sources respectively. Testing this skill ensures that the candidate can effectively use sorting algorithms and understand merging techniques to perform operations like matching records and maintaining data integrity in COBOL programs.
Conditional Statements: Conditional statements in COBOL allow the program to make decisions and perform different actions based on certain conditions. Measuring this skill helps assess the candidate's ability to write accurate and efficient conditional statements to control program flow and make logical decisions in COBOL.
Subprograms and Functions: Subprograms and functions in COBOL are reusable code segments that can be called from different parts of a program. Evaluating this skill is essential to determine if the candidate can effectively modularize code, improve code maintainability, and reuse logic in COBOL programs.
Error Handling: Error handling in COBOL involves handling and reporting errors or exceptions that occur during program execution. Measuring this skill helps determine if the candidate can identify and handle errors gracefully, ensuring that the program continues to run smoothly and provides appropriate error messages or recovery mechanisms in COBOL.
