//
// DESCRIPTION
//
//  This example program is a grab bag that uses several of the
//  archive status and informational functions.  You open
//  an archive by clicking on it from a list box, then see
//  all the information regarding that archive.
//
//  Note that this program checks for duplicate entries in an archive.
//  You might have to fiddle with the examples here in order to get
//  one with a duplicate entry, because we try to avoid that.  I
//  created a duplicate entry by using a binary file editor and just
//  changing the name of an entry stored at the end of the archive.
//
// REVISION HISTORY
//
//  February 1, 1996  2.0A  : Second release
