ASQL_NULL_ALPHA_SPACES allows you to determine how NULL data being returned to an ALPHA field is handled. In some cases, you may want the NULL data returned as ALL SPACES, or you may want the NULL data returned unchanged. Set this variable to the non-default value of TRUE if you want NULL data returned to an ALPHA field as ALL SPACES. The default value is FALSE, and will return NULL data to an ALPHA field unchanged.
