@ (Specify a Compiler Response File)

Specifies a compiler response file.



A text file containing compiler commands.

A response file can contain any commands that you would specify on the command line. This can be useful if you are working on a machine (Windows 95, Windows 98, Windows 98 Second Edition, Windows Millennium Edition) and your command-line arguments exceed 127 characters.

It is not possible to specify the @ option from within a response file. That is, a response file cannot embed another response file.

From the command line you can specify as many response file options (for example, @respfile.1 @respfile.2) as you want.

To set this compiler option in the Visual Studio development environment

  • A response file cannot be specified from within the development environment and must be specified at the command line.

To set this compiler option programmatically

  • This compiler option cannot be changed programmatically.
