The verify property requires users to enter data in the field twice to reduce the probability of erroneous data entry.
This property supplies an additional step in data entry to ensure the integrity of your data. After the user enters a value into a verify field and presses RETURN, the runtime system erases the field and requests reentry of the value. The user must enter exactly the same data each time, character for character: 15000 is not exactly the same as 15000.00.
The VERIFY property takes effect in INPUT or INPUT ARRAY instructions only, it has no effect on CONSTRUCT statements.
