Obsolete Syntax
... sum(field) ....
Effect
For the fields field1 field2 ... of the field groups of an extract dataset, automatically data objects named sum(field1) sum(field1) ... of the same data type as field1 field2 ... are created. These fields can be accessed only within a LOOP and are filled with values for sorted extract datasets using the statements AT END OF and AT LAST.
If the fields sum(field1) sum(field1) ... are accessed without the extract dataset first being sorted, a non-handleable exception can be raised.
