Intel X64 Assembly Level language

[shadab_khatib]

Hello
After having the knowledge about the Intel 8086 programming, I would like to take a step ahead and learn the X32 and X64 bit ASM programming.
From where should I begin for this task and is MASM enough to assemble these programs or will i require any other assembler to do so?
Please reply

You can use Visual Studio 2010 to assemble x86 and x86-64 code,also NASM assembler will suit your needs for 64-bit coding.You can check also MASM32 project i'am using it for simple assembly windows programming.
There are other assemblers too:
GoAsm
YASM
TASM
look here http://en.wikipedia.org/wiki/List_of_assemblers
I will also recommend you a good introductionary 64-bit assembly programming under linux
