your question is not very clear -- what exactly do you want to do? This will move a binary file into ax register

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
u did't understand me.I meant converting instructions into binary like,
int mayb 10111 in binary conversion, u get right?
like all the machines codes to binaries.or a program into bin file. give me the equivalent of the codes in binaries

They're called opcodes it and depends on the processor.

It is true that some genius at AMD had the bright idea of reassigning the opcode for the inc instruction, so that is no longer available on 64 bit processors running in 64 bit mode, but otherwise opcodes generally don't change.

some background:
3.12 Bit Fields and Packed Data

the "Y86" encoding explained:
5.3 Basic Instruction Design Goals

Then look at Daniel Sterling's SML: Simple Machine Language

You also might want to do some basic research into compiler construction. Here are a few usefull links:
