When compare mode C = 0 is used, the content of the search line or search column must be
sorted in ascending order. If the search concept is smaller than the first element or greater
than the last, the value 0 or a blank string is output and the error variable ERR is set to
TRUE.
When compare mode C = 1 is used, the search concept must be present in the search line
or search column. If the search concept cannot be found, the value 0 or a blank string is
output and the error variable ERR is set to TRUE.
