These clauses can be used in the data description entry of the Data Division but must be used only with elementary data items.
Elementary data items are the most basic subdivisions of a record as they are not subdivided into higher level data items.
You have used one of these clauses in conjunction with a non-elementary data item (that is, one which contains higher level
data items).
Resolution:
Revise your program to ensure that these clauses appear only with elementary data items.
