/*
* copy
*/
 
/* /A - Used to copy ASCII files. Applies to the filename preceding it and to
* all following filenames. Files will be copied until an end-of-file mark is
* encountered in the file being copied. If an end-of-file mark is encountered
* in the file, the rest of the file is not copied. DOS will append an EOF
* mark at the end of the copied file.
*
* /B - Used to copy binary files. Applies to the filename preceding it and to
* all following filenames. Copied files will be read by size (according to
* the number of bytes indicated in the file`s directory listing). An EOF mark
* is not placed at the end of the copied file.
*
* /V - Checks after the copy to assure that a file was copied correctly. If
* the copy cannot be verified, the program will display an error message.
* Using this option will result in a slower copying process.
