One thing you
ll realize immediately is that the disassembly window can be a big help
in beginning to understand what assembly language is all about. I wish I had more
time to go over each statement, addressing modes, and whatnot, but there are better
resources for that anyway.
Notice first the structure of the disassembly window. The column of numbers on the
left-hand side of the window is the memory address of each instruction. The list of
one to ten hexadecimal codes that follows each address represents the machine code
bytes. Notice that the address of each line coincides with the number of machine code
bytes. The more readable instruction on the farrightistheassemblerstatement.Each
group of assembler statements is preceded by the C++ statement that they compiled
