| The file being empty, the 'AT END ' clause will be executed |

Hi,
There are 2 kinds of empty:
1) If the file was never opened/closed, it is uninitialized and not a valid file.
2) If it was opened/closed but never written to, it is a valid file with no records.
In the 1st instance, if you attempt to open the file, it will produce an error.
In the 2nd, the open is successful and the 1st read produces an EOF condition. |
