请问如何在批处理文件中获取一个软件的根目录位置，然后将该位置设置成一个环境变量？
例如我想在批处理文件中用"set rarRoot= "来设置rarRoot环境变量为winrar的根目录，然后在后面的程序中使用。该如何实现呢？
谢谢
How to get the root directory location of a software in a batch file and then set that location as an environment variable?
For example, I want to use "set rarRoot= " in the batch file to set the rarRoot environment variable to the root directory of WinRAR, and then use it in subsequent programs. How to achieve this?
Thank you

It makes use of the memory function of the lastkey key value. It's quite good. The inability to locate the specific value is a defect of the registry.

Okay, upload the REG file for 2003 SERVER SP1. http://zhenlove.com.cn/cndos/fileup/files/reg.rar
