There are few things still everyone need to know about an array.

• Arrays have multiple benefits. While reading an i/p file in batch process
• the only way we can store data internally is with arrays. So the data can be used for logical processing within the program

Important points are:

1. 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’

2. 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)
