What Are Different Types Of Cobol?

The data types in Cobol are classified into three types which are as follows:

• Numeric. The numeric data types are used to represent numeric values (0-9) in Cobol programming.

What is the maximum array size in COBOL?

The maximum length of an element of a table is 65280 characters (that is, data items subordinate to an OCCURS clause cannot exceed 65280 characters in length). The maximum number of occurrences of a table element is 65535. That is, in an OCCURS clause, the value of integer-2 must be less than or equal to 65535.
