"The compiler I use is named as MicroVision 2 from Keil Inc."

So why don't you just look in the KeilC51Examples folder on your PC???
or the Examples on the Keil website.

Did you get a CD?
If so, it has a huge collection of app notes, examples, datasheets, and links to loads of manufacturers websites, etc, etc,...

BTW: To be precise, uVision is not a compiler; it is a so-called "Integrated Development Environment" (IDE) that provides you with editor, debugger, project manager, and a graphical interface to the command line tools (compiler, linker, etc)
