If the wiki article is saying that PE is loaded with a dynamic loader then its probably talking about a DLL. It is certialy not the case that all exe's are loaded with a dynamic linker. I don't really need to post a link to prove you wrong because anyone, who has a clue, who reads this knows you are wrong.

You initially started spouting that an exe was not machine code in some kind of attempt to prove that object code was machine code.

The MZ header doesn't change this.

Object files contain object code. It is incorrect to say that an object file is machine code just because the text segment contains opcodes. You can, in the correct context, say that object files contain machine code as the text section notrmally does contain machine specific opcodes. It is incorrect however to suggest this file format is the same as an exectuable. --- Posted via news://freenews.netfront.net/ - Complaints to news@netfront.net ---
