Programs are written to be executed, and the file that you ultimately create in assembly language programming (or most any programming, actually) is called an executable program file Under Linux (as I describe toward the end of this book), there is only a single kind of executable program file In DOS work, however, there are two types of executable program files: COM files and EXE files I deal with both in this book, and the specific technical differences will have to wait until I've covered a little more ground But in purely practical terms, COM files are produced directly by the NASM assembler, whereas EXE files are generated by a linker The linker program may be seen as a kind of translator program, but its major role lies in combining multiple object code files into a single executable program file The linker would accept, for example, three object code files: FOOOBJ, BAROBJ, and BASOBJ, and knit them together into a single executable program file This file would by default be called FOOEXE, but you can specify any name you like to the linker An executable file can be run by typing its name (without the COM or EXE extension) at the DOS prompt and pressing Enter: C:\>FOO

For quite a few years there was only one assembler product in general use for the PC: Microsoft's Macro Assembler, better known as MASM MASM was and remains an enormously popular program and has established a standard for assembler operation on the PC In 1988, Borland International released its answer to MASM in the form of Turbo Assembler, which was quickly christened TASM by syllable-conserving programmers TASM was a great deal faster than MASM and started an arms race with MASM that went on for some years Borland's products (and eventually Borland itself) began losing the race with Microsoft in the later 1990s, and today TASM is no longer available MASM can be purchased from Microsoft, and is included in several of Microsoft's developer product bundles It's an excellent product, and if you go on to do professional (that is, paying) work in assembly language, you're more than likely to be called upon to use it I'm not, however, going to be covering MASM in any detail in this book Something wonderful happened in the mid-1990s that changed the world of software forever The idea of open source software caught fire and caught the imagination of programmers everywhere In open source software, programmers collaborate (generally over the Internet) with dozens or even hundreds of other programmers and create software products that no single programmer (or even two or three) could have produced alone To facilitate the collaborative process (and to eliminate fights over who owns the software), open source software is turned loose with all of its source code and documentation, and made available for free to whoever wants it When the idea first got the attention of the mainstream, it seemed simply nuts Why would programmers do all this work for nothing While some of the founders of the open source movement, such as the estimable Richard Stallman, insist that software should ideally be free for ethical reasons, the practical reality is that the open source concept of free software makes projects possible that would never happen otherwise Many hands are required to create complex software, and the arguments that arise over ownership, marketing, and distribution have killed many good software products that the world could well have used By making software "no secrets" by design and letting anyone who wants it have it, these arguments go away and collaborative effort becomes possible The largest and most visible open source project, of course, is the Linux operating system, begun by Linus Torvalds, a Finnish college student, in 1991 I have a couple of chapters on writing assembly language under Linux toward the end of this book But the big win for us assembly language geeks is that in 1997, an open source assembler appeared Its name is NASM, the Net-Wide Assembler, and it has improved relentlessly since its first release Now, in 2000, it is brutally effective, easy to learn, and best of all, it's still free I explain lots more about NASM through the course of this book, but you should fire up your Web browser and go look at the NASM Web site at wwwweb-sitescouk/nasm/toolshtml In case the copy of the book you own no longer has the CD-ROM in it, or if the CD-ROM is damaged or otherwise unreadable, you can download NASM from this Web site and many other places The version of NASM I'm using throughout this book (the one that is on the CD-ROM) is 098 If you have an older version from somewhere, please obtain the 098 release so you don't get confused when I talk about features that don't exist in your copy! Most commercial assemblers (such as MASM and TASM) come with their own special debugging tools, called debuggers MASM's debugger is called CodeView, and TASM's debugger is called Turbo Debugger Both are enormously sophisticated programs, and I won't be discussing either in this book, in part due to their intimate connection with their associated assemblers, but mostly because there is a debugger shipped with every copy of DOS and Windows even Windows NT This debugger, simply named DEBUG, is more than enough debugger to cut your teeth on and will get you familiar enough with debugger concepts to move up to a commercial debugger later on I describe DEBUG much more fully in a following section
