uncheckedValue

The Unchecked Value property is used to specify the value that will be passed to the variable associated with the checkbox, when this checkbox is unchecked.

During the INPUT WITHOUT DEFAULTS and DISPLAY statement execution the checkbox will be initially displayed as not marked if the value of the corresponding variable matches the one specified in the Unchecked Value property.

Remember, that the data type and format of the specified Unchecked Value must correspond to those of the variable bound to the field.
