Question

1. When I debug an EXE in it,will first stop on a specific line,how does OD know where to initially stop?
2. And the disassembly code is pretty short, is it true that OD only displays stuff within a single memory page? If true,how can I make it show all stuff?

Answer 1

1. It stops at the entry point of the code i.e., the place where the exe starts execution. Theres an entry point defined in every EXE.
2. I don't think that is true. It shows all the code.

Answer 2

1. you can configure where it should stop. by default it stops on the program entry point mentioned in the PE header.

2. You can open the memory map and open any page listed there either in the dump window or in the disassembly. You can also follow any jump in the disassembly. So you can see all code.
