This instructs DB2 to pass the index keys to the sort program in memory, rather than having the keys written to and read once again from sort work files on DASD.

这将指示DB 2将索引键传递给内存中的排序程序，而不是再次将这些键写到DASD上的排序工作文件中，然后从中读取这些键。

If you write a half-dozen programs, each of which sorts lines, you can end up having to fix similar bugs half a dozen times instead of having one better-maintained sort program to work on.

如果您编写半打程序，其中每个都对行排序，您最终可能必须六次修复六个类似的bug，而不是去使用一个得到更好维护的sort程序。
