Windowed operating environments

Clicking this button opens the Printer Setup dialog box through which the user can select the output device from a list of all devices known to the MS-WINDOWS operating environment. 

Every operating system or operating environment (such as Windows 9x or Windows NT) has certain key system files that must be present in order for it to function. If these files are missing or corrupt, the operating system will cease to function properly. Files can be deleted by accident rather easily, so it s important to know what these system files are, where they are located, and how to replace them. 

SYSTEM.INI In Microsoft Windows, an initialization file that contains information on your hardware and the internal Windows operating environment. 

The validation of analytical methods is a well-known problem in the analytical community [1], The international guidance for equipment qualification (EQ) of analytical instruments and their validation is in the development stage [2-4], At this time validation of computer systems for analytical instruments is less elaborated [5-7], The term computer system comprises computer hardware, peripherals, and software that includes application programs and operating environments (MS-DOS, MS-Windows and others) [5, 6], Since programs, software and the whole computer system are elements of the instrument used by the analyst according to the analytical method, successful validation of the method as a black box [8] means successful validation of the instrument, computer system, software and programs. On the other hand, the same instrument may also be calibrated and validated as a smaller (in-... 

Recommendation 15. The Chemical Materials Agency should conduct an overall evaluation of security requirements, maintenance implications, and impending evolutionary changes in the basic computer operating systems (Windows and Linux) used at chemical agent disposal facilities. A migration path that drives toward a minimally heterogeneous and maximally robust environment should be identified and considered for implementation. (Tier 3)... 

The operating environment on the desktop workstation wih be a windowed, graphical user interface as iUustrated in Figure 3, for access to both local workstation and remote host apphcation software. Users wih require such interfaces for many reasons, including responsiveness, high quality graphics and colour, WYSIWYG presentation, ease of use, and so forth. People who have used such interfaces wih not return either to terminals or to any user interface that... 

MATLAB The programs contained on this CD-ROM have been written in the MATLAB 5.0 language and will execute in the MATLAB command environment in all three operating systems (WINDOWS, Macintosh, and UNIX). Version 5.0 or higher, including the Student Edition, is sufficient to run the programs. 

Powerful operating environments are already available. Most are in the general category of WIMPs , Windowed, Icon-based, Mouse-driven, Pointing systems. Developers of application software are moving their applications into these environments rapidly, to take advantage of the benefits that result. 

Standards are emerging for operating environments. For example, Microsoft Windows and its close relatives, including Windows/286, Windows/386 and the Presentation Manager, provide an operating environment that is similar across many different machine in the MS-DOS and OS/2 worlds. X-Windows is emerging as a standard in the UNIX and VMS worlds. Hewlett- Packard (HP) has announced New Wave, an operating environment based on the Microsoft Windows architecture. These environments are incompatible, but they at least offer some similar functionality and appearance to the end-user. 

The advent of operating environments that are fewer in number than the number of operating systems will improve the situation. I expect that the chemical community will follow the computer industry and standardize on a small number of OEs. I expect that the following OEs will find favor in the community, and be chosen by developers as the platforms on which to build the next generation of software for chemical applications (1) Microsoft Windows for high speed 80286 and 80386 DOS machines (2) Windows cousin, the Presentation Manager, for 80286 and 80386 OS/2 machines (3) Finder and Multi-Finder for the Macintosh (4) X-Windows and toolkits for UNIX machines and (5) DECWindows for DEC/ VAX/VMS. 

Low-level ventilation openings, whether windows, doors or ventilators, are generally manually operated for simplicity and economy, allowing personnel to control their own environment. High-level openings can also be manually controlled by means of rod or cable operation, although this has generally lost favor (except in the case of simple windows) and automatic operation is preferred. 

All programs are intended to be run as application on a PC using the Windows operating system (XP or later). The code was written in FORTRAN 90/95 and compiled with the INTEL Visual FORTRAN compiler integrated in the Microsoft Visual Studio Developer Environment.
