file object
The file object is used to read and write files stored on the hard disk.
file()
Parameters:
None.
Remarks:
The file object is initially blank, until a file is associated with it. To associate a file you must call the "open" method specifying a name or a path for the file, and the mode in which the file is opened. You may call the "open" method again at any time if you wish to open a new file, at which point the old file (if any) will be cleared. This, in short, allows you to reuse the same file object to control multiple files.
Example:

    // Write some text into a file.

    void main()
    {
    file test;
    test.open("c:\\test.txt", "w");
    test.write("I am a text file!");
    test.close();
    }
