Intrinsic Functions

Intrinsic Functions

An intrinsic function is a function that performs a mathematical, character or logical operation to a variable whose value is derived automatically during the program execution.

The functions can be grouped into six categories based on the type of service performed. They are - mathematical, statistical, date/time, financial, character-handling and general.

A function can be used by specifying its name along with required arguments in a Procedure Division statement. Functions use elementary variables and return alphanumeric, numeric, integer, Boolean or date-time values. Functions cannot serve as receiving operands.
