Hello everyone,
Someone recommend me to use Microsoft Macro Assembler 8, I have already installed it, together with Microsoft Visual C++ 2005 but I don't know how to use it.

Can someone guide me please, I tried to search some tutorial on the net but can't find for this program. I am a beginner to assembly language.

Thanks in advance.

In my opinion its better to start with fasm . Its open and has some good documentation on the main site . (flatassembler.net)
But to learn it try searching for "iczelion win32" tutorials (they are for masm btw).
