DOS/4G. Obviously, it is a solution for DOS programs to use 4G memory. Do you still remember the legend of doom, C C, Red Police, and Jin yongqun Xia? When the program runs, it will display a line of "dos/4GW...", which is a game written by Watcom C ++. Because the game industry requires a large array of memory, texture, and sound processing. If the array is used in multiple parts, the programmer is too tired to execute such a large program. Well, D

the new kernel. After setup finds this, it will stop. According to the specification, you should write it as 0xff, which indicates the unknown boot loader. If your bootloader has an officially assigned type id, write your own value. 6. Details 2: how to load the kernel If your current environment is nothing, you must use the bios interrupt or ATA command to read the hard disk. However, if you have a basic DOS system, you can use the DOS program. In order to be able to operate the entire 4 GB

Watcom C uses trailing underscores for function names, and leading underscores for global variables.If your GCC supports it, leading underscores can be turned off with the compiler Option-fno-leading-underscorePascal Calling conven

Preface------- The PE ("portable executable") file format is the format of executableBinaries (DLLs and programs) for MS Windows NT, Windows 95 andWin32s; in Windows NT, the drivers are in this format, too.It can also be used for object files and libraries. The format is designed by Microsoft and standardized by the TIs (ToolInterface Standard) Committee (Microsoft, Intel, Borland, Watcom, IBMAnd others) in 1993, apparently based on a good knowledge o

C language is the most popular and widely used high-level programming language in the world.C language is better than other advanced languages for operating systems and system programs and hardware operations. Many large applications are written in C language.The C language has strong plotting ability, portability, and strong data processing capabilities. Therefore, it is suitable for compiling system software, 3D, 2D graphics, and animation. It is a high-level language for numerical computing.C

watcom technology used by PowerBuilder is mainly 32-bit technology, although there are options for generating 16-bit code on 32-bit platforms, but the speed is not good. On the 16-bit platform, we cannot produce 32-bit applications. One of the limitations of compiling a 16-bit application is that neither the code nor the data can exceed 64K, and if the code in the function or event is too long, PowerBuilder will generate an error when creating the EX
