Redirecting Errors to a File

By default, MVC displays all errors on your screen. However, you can redirect errors to a file so that you can examine the errors more carefully and fix problems in your title. You can examine the redirected file by using any ASCII text editor. Use the standard MS-DOS redirection syntax to redirect error and status messages to a file; for example:

MVC USA.MVP > MSG.TXT

This command places all the messages sent during the build process into the MSG.TXT file. You can also enter the following option in the [OPTIONS] section of your project file:

ERRORLOG = error-file

MVC places compilation errors in the file given by error-file. The error-file can be an absolute or relative path if the file does not appear in the standard Viewer directory. Using ERRORLOG has two advantages over redirecting error messages:

Using redirection, MVC puts unnecessary characters (including the periods it displays to indicate the progress of the build) and status messages along with error messages in the output file. Using ERRORLOG, you only get error messages.

Using redirection, MVC doesn't display error messages on the screen, so you can't monitor the messages during the build. Using ERRORLOG, MVC displays the error messages on your screen as well as writing them to the file.
