Predefined Field Region Description Variables

Name	Description
`IsNull`	Variable of type Logic. The value of the variable determines whether the field region has been found or not. The IsNull variable is pre-initialized with value `False`, which means that the field region has been found. To instruct the program that the block has not been found, set the value to `True`. Used for fields of all types.
`IsSuspicious`	Variable of type Logic. Its value indicates whether the field has been detected reliably. The IsSupicious variable is pre-initialized with value `False`, which means that the field has been found. To tell the program that the field has been detected unreliably, set the value to `True`. Used for fields of all types.
`OutputInstances`	Variable of type HypothesisInstances that is used for fields of the Repeating Group type. The value of the variable defines the detected field region. The region of a field built from the instances of elements and subelements of a repeating group is discontinuous.
`OutputRegion`	Variable of type Region. The value of the variable determines the region of the block.
`OutputValue`	Variable of type String. Allows you to set the value of the field as a string. Can be set when the field region is not set.
