摘要

此更新中最重要的更改是添加了子命令细分，它会发布关于不同缺失值的报告；也就是说，如果包含字符串变量，则数字显示为1）空字符串“”；如果包含数字变量，则显示为2）系统缺失和扩展缺失值。此子命令在检查数值变量是否存在扩展的缺失值时非常有用。

Software Updates

The most important change in this update is the addition of the subcommand breakdown, which issues a report on different missing values; that is, the numbers present as 1) empty strings "" if string variables are included and 2) system missing and extended missing values if numeric variables are included. This subcommand is most obviously useful as a check on the presence of extended missing values for numeric variables.
