那Logical File 又指的是什么呢?
PF SF LF 这三种类型的文件会在什么地方用到他们,能举举例子看嘛?
谢了

SRCF是存放代码的 是PF的一种 类型为PF-SRC
PF还有一种为类型为PF-DTA的,他是用来存放数据的,SRCF中的MEMBER可以编译出PF-DTA类型的PF
LF就是逻辑文件(视图 VIEW),他是Base on在PF-DTA类型的PF的
如果你不知道VIEW是什么,建议你先看看关于数据库方面的书

For your information,
1. Object Type: *FILE --> One is PF, another is LF.
2. Physical File's Attribute --> One is PF-SRC, another is PF-DTA.
3. Source Physical File is a collection of source members.
4. Data Physical File is a collection of data.
5. System will generate a PF-DTA object after compile a member of PF-SRC (if it's a DDS source).
6. System will generate a program object after compile a member of PF-SRC (if it's a HLL source).
