The built-in functions performs specific processing based on the values of several arguments and returns the result to the program.
The value of the function is called the "function value."

The built-in function module can be used in a statement in the PROCEDURE DIVISION. To use the built-in function module, write a function-identifier in the statement.

The following table lists the built-in functions that your compiler probably will support.
