## AT END OF DATA Usage

The `AT END OF DATA` statement is used to specify processing to be performed when all records selected for a database processing loop have been processed.

This section covers the following topics:

- Processing

- Values of Database Fields

- Positioning

- System Functions

See also AT START/END OF DATA Statements in the Programming Guide.

### Processing

This statement is non-procedural, that is, its execution depends on an event, not on where in a program it is located.

### Values of Database Fields

When the `AT END OF DATA` condition for the processing loop occurs, all database fields contain the data from the last record processed.

### Positioning

This statement must be specified within the same program module which contains the loop creating statement.

### System Functions

Natural system functions may be used in conjunction with an `AT END OF DATA` statement as described in Using System Functions in Processing Loops in the System Functions documentation.

## AT END OF DATA Restrictions

- This statement can only be used in a processing loop that has been initiated with one of the following statements: `FIND`, `READ`, `READ WORK FILE`, `HISTOGRAM` or `SORT`.

- It may be used only once per processing loop.

- It is not evaluated if the processing loop referenced for `END OF DATA` processing is not entered.

## AT END OF DATA Syntax Description

Syntax Element | Description
--- | ---
`(r)` | Reference to a Specific Processing Loop: An `AT END OF DATA` statement may be related to a specific active processing loop by using the notation `(r)`. If this notation is not used, the `AT END OF DATA` statement will be related to the outermost active database processing loop.
`statement ...` | Statement(s) to be Executed at End of Data Condition: In structured mode, you must supply one or several suitable statements, depending on the situation. For an example of a statement, see Example below.
`END-ENDDATA` | End of AT END OF DATA Statement: In structured mode, the Natural reserved word `END-ENDDATA` must be used to end the `AT END OF DATA` statement. In reporting mode, use the `DO ... DOEND` statements to supply one or several suitable statements, depending on the situation, and to end the `AT END OF DATA` statement. If you specify only a single statement, you can omit the `DO ... DOEND` statements. With respect to good coding practice, this is not recommended.
`statement ...` `DO statement ... DOEND`
