Specifying stdout or stdin allows ontape to use pipes (an OS provided buffer mechanism to connect separate programs to a data stream) for archives and restores.
可以指定stdout或stdin，允许ontape在存档和恢复的过程中使用管道（OS提供的一种缓冲机制，将不同的程序连接起来传递数据）。
Starting with IDS v10, ontape operations can now be directed to or from "standard in" or "standard out" (STDIO), thereby providing support for a wider range of options.
从IDSv10开始，ontape操作可以被定向到标准输入或标准输出设备(“standardin”或“standardout”，STDIO)，因此为很多选项提供了支持。
