关于400上的object解释。

dlms

库是不是一个object呢？
今天看一个文档上写的一句话。“库是一种目标，是唯一一种可包含目标的目标"，不知道这种说法是否正确

其实只要用命令WRKOBJ能看到的东东都是。

ux400

A library (*LIB) on the AS/400 is an object that is used as a system directory to keep track of other objects. (It is also keeps track of PTFs in AS/400 system libraries.) (The other directories that can be used are the directory (*DIR) and folder (*FLR) objects.)

Objects are not actually stored in libraries. They're really nothing more than namespaces, but it's easier to refer to an object as being "in" or "stored in" a library.

Certain types of the object (database file, storage areas and executable program objects) can be compiled, copied, and stored into/from many different libraries concurrently, with the Library List hierarchy determining which instance of the object to use during execution of any application that utilizes that object name. There are commands to help move objects around, and objects may be qualified at compile time to point to specific other objects statically at runtime, in order to circumvent the Library List.

Other types of objects, designated as "system" objects cannot be replicated. Libraries are a "system" object, and therefore only one instance of any given Library "name" is possible. They're made to appear as if they're stored in the QSYS library. Other "system" objects include user profiles (*USRPRF), configuration objects (*LIND, *CTLD, & DEVD), etc.

object首先要有NAME，并且占用硬盘空间，是在存放在库下面的，当然Library也是object，400是单级的库结构，Library下面是不能再出现Library的，但实际上所有的Library也是在QSYS这个根下面的，而且定义object有个关键因素是object是有类型的，你可以看到Library的类型就是*LIB，名字就是LibraryName，肯定会在ASP中占用空间，所以Library也是个object。

我的理解是说的是准确的

当初我曾经不把LIB当OBJECT。

OBJECT翻译成对象会比较好理解一些。。。。
