Let <R> denote the start of record and </R> the end of the record. One has <R>5</R><R>6</R><R>7</R> After reading '5', the file is positioned to after that record. If * denotes the current file, then one can have <R>5</R>*<R>6</R> or <R>5</R><R>*6</R> Both meet the requirement of 12.3.4.4. Now by 12.8.3, the endfile will give <R>5</R>EOF while the latter would give <R>5</R><R>*6</R>EOF.
