Arrays have multiple benefits. While reading an i/p file, in batch process, the only way you can store data internally is in arrays. So, the data can be used for processing within the program. Related[COBOL PERFORM Until Vs Times](https://srinimf.com/2017/01/17/cobol-logic-with-complex-question-newly-asked/) [COBOL Arrays](https://srinimf.com/2015/10/05/java-collections-for-mainframe-programmers/) Important points are: ## Point1: 01 Array-example      02 Table-1 occurs n times             03 Field-1    pic x(2)             03 Field-2  pic x(3) Here the ‘n’ times is any value from ‘1’ to ‘32767’ ## Point 2: We know arrays are fixed length, variable length. While working with DB2, the array must handle BLOB and CLOB (Binary large object and Char Large object) You can see the syntax from IBM site [here](http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.db2.doc.apsg%2Fbjnqcobl2189515.htm). ## LATEST POSTS [![30 SQL Practice Queries with Solutions — Run Them Live](https://i0.wp.com/srinimf.com/wp-content/uploads/2026/10/pexels-photo-5530473.jpeg?fit=867%2C1300&ssl=1)](https://srinimf.com/2026/10/01/30-sql-practice-queries-with-solutions-run-them-live/) ## [30 SQL Practice Queries with Solutions — Run Them Live](https://srinimf.com/2026/10/01/30-sql-practice-queries-with-solutions-run-them-live/) Practice 30 SQL queries with solutions, from SELECT and JOINs to subqueries and window functions.
