VESA VBE Framework Computers, Inc. preserves companies' intellectual property by customizing the Framework Windows compiler with custom functions to allow transparent compilation of non Windows programs' source code to create Windows GUI programs.
After the compiler is modified for a specific non Windows program the source can be compiled into a Windows GUI programs with no modifications to the original source. The code and can run, maintained, as well as modified and extended taking unlimited advantage of Windows XP, 2000 and Vista GUI API.
Intellectual property written for other operating systems including real and protected mode DOS, SUN, Apple MAC, Unix, Mainframes and database operating system can run on Windows with full access to the Windows GUI, API, controls, Direct X and the messaging system. The compiler provides a much simpler way to program with a function-based alternative interface to Windows API. It can be used to extended programs with Internet access, communication with other Windows program, DLL calls, MS SQL, ODBC database and OLE. Scalable font, graphic interface, hardware based software protection, and automated distribution and billing libraries are available for intellectual property that is distributed commercially.
The compiler can be customized to transparently compile a non Windows program into a Windows GUI executable even if the programs directly access hardware for functionality such as measurement, communications, and real time control systems.
The advantages in compilation of original source code are obvious compared to the complexity of the Windows API. Windows treats all programs as downloaded libraries, and requiring applications to provide entry point to the OS, scan system messages, self manage the system focus changes, and manage background screen updates. These Windows complexities become transparent by the compiler's alternative function based API. Companies can preserve irreplaceable intellectual property investments while gaining the ability to extend the applications with Internet functionality and there by increase potential while maintaining full control over the IP.
The compiler adaptation is available for Windows XP, Windows 2000, and Windows Vista.

FrameworkPascal Multi-target 2008 ver 6.10, commercial subscriptions. 2008.
FRAMEWORKPASCAL 6.1 (2008) provides code compatibility with minimally required code adaptation between DOS and Windows GUI including Windows XP, Windows 2000, and Windows Vista. An alternative function based Windows GUI API interface replaces the event driven messaging Windows system to provide DOS like interface to the operating system and automatic transparent focus and background graphic management without the need to interface with the Windows messaging system and with much simpler to programs graphic and user interface functions API.
