Hi,

My question is concerning indicator variables.

#################### Text : BEGIN #####################

You can associate any host variable with an optional indicator variable. An indicator variable is a short integer variable that "indicates" the value or condition of its host variable. You use indicator variables to assign nulls to input host variables and to detect nulls or truncated values in output host variables. A null is a missing, unknown, or inapplicable value.

Why do we have to use _special_ (indicator) variables? Is not there any possibility to manage only with host ones?
