Hello,
Please refer any book for MASM32. I have a complete knowledge about the assembly for 8085, 8086, 8051. Now,I am ready to work with some of the assembler. Please refer any book for a good start and exploration.
If you already know 8086 there is little need for a book.
Explore the many examples of code to get the layout and syntax and you're all set :wink
If you are looking for MASM documentation, have a look at :
