As an alternative to placing all the options associated with a switch on the command line, the MIDL compiler accepts response files that contain switches and arguments.
A response file is a text file containing one or more MIDL compiler command-line options. Unlike a command line, a response file allows multiple lines of options and filenames. This is important on systems such as MS-DOS, which limit the number of characters in the command line.
Options in a response file are interpreted as if they are present at that place in the MIDL command line.
Each argument in a response file must begin and end on the same line. The backslash character ("\") cannot be used to concatenate lines.
When it is part of a quoted string in the response file, the backslash character can only be used before another backslash (\or before a double quotation mark character ("). When it is not part of a quoted string, the backslash character can only be used before a double quotation mark character.
MIDL supports command-line arguments that include one or more response files combined with other command-line switches.
The MIDL compiler does not support nested response files.
