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:
See also AT START/END OF DATA Statements in the Programming Guide.
This statement is non-procedural, that is, its execution depends on an event, not on where in a program it is located.
When the AT END OF DATA condition for the processing loop
occurs, all database fields contain the data from the last record
processed.
This statement must be specified within the same program module which contains the loop creating statement.
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.
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.

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

Statement(s) to be Executed at End of Data Condition:
