VERIFY
The VERIFY attribute requires users to enter data into the field twice, in
order to reduce the probability of erroneous data entry.
field-tag is the field tag that you declared in the SCREEN section.
Since some data are critical, this attribute 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, 4GL 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 attribute takes effect while INPUT, INPUT ARRAY, or UPDATE
statements of 4GL are executing. It has no effect on CONSTRUCT statements.
