If you want to avoid the exception, then the data must be truncated to fit the field and you must code additional logic to do the truncation.

如果您希望避免该异常，则必须将数据截断以适应该字段，并且必须编写附加的逻辑代码来处理截断。

The new 8-byte DIF field includes a cyclical redundancy code (CRC) to protect the data, a reference tag to protect against misdirected writes, and an application tag.

这个新的8字节dif字段包括一个循环冗余代码(CRC)用以保护数据，一个参考标签用以保护数据免遭误导写入，以及一个应用程序标签。

As it is, though, the code doesn't do anything to make sure that clumsy users or programmer bugs don't cause incorrectly formatted data to be put into the number field.

尽管如此，代码不能确保笨拙的用户或程序员漏洞不会导致未正确格式化的数据放入number字段中。

It is also tricky to capture the data in the field and stick the bar-code labels on the produce as it is picked and packed.
