 * Sample program that uses the FileFactory class to copy a text file or dataset.
 * The input and output file names are given as arguments to main,

 * <p>
 * If the target file is an MVS dataset, then its LRECL should be compatible
 * with the source file/dataset. 
 * <p>
 * Example file names:
 * <ul>
 * <li>/etc/profile</li>
 * <li>//DD:INPUT</li>
 * <li>//'SYS1.MACLIB(ABEND)'</li>
 * <li>//MY.DATASET</li>
