What is the .CV4 File Extension?

.CV4 File Extension Description:

The file extension .cv4 is associated with the CodeView software application, which is described as the standalone debugger developed by David Norris during his tenure in Microsoft as a component of the development toolset released by the company. The .cv4 file extension was originally shipped to the market packaged under the Microsoft C 4.0 including subsequent version releases. Aside from the Microsoft C, the file extension .cv4 was also packaged with the Visual Basic for the MS-DOS environment and the Microsoft BASIC PDS including other development environments released by the company. The file extension .cv4 was closely identified with the color configuration feature of the application and supported its full screen functionality orientation, which was a first for the MS-DOS environment based debuggers that at the time were primarily line oriented.

The implementation of the file extension .cv4 diverted from the standards presented in its processor debuggers like the symdeb and the DEBUG.COM. Execution of the CodeView presents the user with several open window options, which could be arranged in a tiled manner or moved to other locations on the desktop, including other appropriate object manipulation actions. The .cv4 file extension supports the Code window, which shows what code is currently being debugged in the context of the source code.

Other .cv4 file extension-supported windows also include:

•the Data window, which represents the hexadecimal dump based on the memory specified by the user;

•and the Command window, which contains the user commands that implement the basic syntax similar to those utilized by symdeb and DEBUG.COM.

The latter window serves as an input window for the associated commands of the debugger application. The functionality provided by the file extension .cv4 was incorporated into a single integrated development environment, with the introduction of the Microsoft Visual C++ language.

The file extension .cv4 functionality remains available for Visual C++'s 16-bit versions, including support for QuickC and a host of other development tools included in the Quick Series. The .cv4 file extension's integration was widely accepted by majority of developers because it eliminated the need to switch between a coding and a debugging software application.
