// DESCRIPTION
//
//  This example program gives a brief listing of an archive's contents.
//  If you don't specify an archive name on the command line, by
//  default it will display the contents of DOS00.GAL.  If you don't have a
//  copy of DOS00.GAL already, you can create one using EX00CON.
//
// REVISION HISTORY
