How to write few asembly lines, during C programming for 89C52

Thanks, but I'd tested
#pragma asm
#pragma endasm

before, and I could not use it. Do you have any example of using it?

"I could not use it."

What happened?
Why couldn't you use it?

"Do you have any example of using it?"

There are examples in the manual

You did remember the SRC directive, didn't you...?

//here is a sample of Keil C51
main()
{
#asm
mov a,b
#endasm
}
// and you must set two options about
'SRC..' of this file. To right hit this
file in the file tree -->Options for file..

The manual?
Where can I get it? THANKS.
