Created a dbf table .

tried inserting data in date field , when invalid dates are entered in correct 
date format with separators like 56/56/56 and saved , no error message is 
thrown.
when i try to enter values in next record the invalid date is replaced with 
default date 12/30/99.
when same invalid date is given without separators like 565656 and saved still 
no error message is thrown .
but default date is replaced when i try to enter values in next field.



and when the query is run , after entering the invalid date fields , still it 
is displaying invalid dates .

like select * from table_name;

the invalid dates entry is given in attachment
