Two new macro systems support UNICODE text that can be used in much the same manner as embedded ASCII text. DEP Compatibility The MASM32 SDK has been rebuilt to ensure it is fully compatible with the Data Execution Prevention safety feature in later versions of Windows. OS Version The MASM32 SDK requires Win2000 or higher Windows versions. The Installation is not designed to run on Win9x or ME. Features 1. The most up to date version of Ray Filiatreault's floating point library and tutorial. 2. A completely new dedicated time and date library written by Greg Lyon. 3. The MASM32 library with over 200 procedures for writing general purpose high performance code. 4. A new dynamic array system for variable length string and binary data with both a macro and procedural interface. 5. The include files and libraries have been upgraded to include VISTA / Win7 with additional equates and structures. 6. A specialised linker, resource compiler and assembler from Pelle's tool set with working examples. 7. An extensive range of example code ranging from simple examples to more complex code design. 8. Prebuilt scripts in the editor for creating working templates for assembler projects. 9. A very easy to use console interface for developing algorithms, test code and experimental ideas in code. More ...... Target Users The MASM32 SDK is targeted at experienced programmers who are familiar with writing software in 32 bit versions of Windows using the API interface and who are familiar with at least some direct mnemonic programming in assembler. It is not well suited for beginner programmers due to the advanced technical nature of programming in assembler and beginners are advised to start with a compiler first to learn basic concepts like addressing, programming logic, control flow and similar. Help Files The help file system has been upgraded to CHM format so that MASM32 can be used on Windows versions that no longer support Winhelp help files. Application MASM is routinely capable of building complete executable files, dynamic link libraries and separate object modules and libraries to use with the Microsoft Visual C development environment as well as MASM. It is an esoteric tool that is not for the faint of heart and it is reasonably complex to master but in skilled hands it has performance that is beyond the best of modern compilers when properly written which makes it useful for performance critical tasks. Things To Get For both space and copyright reasons the MASM32 SDK does not include reference material from either the Intel Corporation or the Microsoft Corporation but both make the best comprehensive reference material available as free downloads. With the Intel Corporation you would obtain the PIV set of manuals or later for compete mnemonic and architecture reference and with the Microsoft Corporation you can either use their online MSDN reference or download an appropriate PLATFORMSDK or its successor for you own version of Windows. If you can still find it, it is useful to have the very old WIN32.HLP file on your computer even if you have to download the Winhelp engine to use it on OS versions like Vista as it is a lot faster to load than the later CHM format help files and works with the F1 help key system built into the default editor. Useful Links for Assembler Programmers Warning Not for the faint of heart. If MASM is beyond you, take up server side scripting.
