RPG uses a 1 character field (like an indicator) to determine if a column contains nulls.───RPG 使用一個 1 字符字段(比如一個指示符)來確定列是否包含空值。
If the latter is true, then the indicator variable for that column is set to -5 which will set the column to the default value for that column.───如果是后一種情況,那么該列的指示符變量被設置為- 5,這將把該列的值設置為默認值。
If the former is true, then the indicator variable for that column is set to -1 which results in the column being updated with the null value.───如果是前一種情況,那么該列的指示符變量被設置為- 1,這導致該列被更新為空值。
