 		 #143577 - No, don\'t do that!

one simplest way is to use #pragma ASM and #pragma ENDASM.

It may seem "simple", but it is generally best avoided.

It has many pitfalls, eg see: http://www.8052.com/forum/read.phtml?id=143387

It is generally far better to write an assembler function and call that from 'C'.

In fact, that's what this whole thread has been about!
