 *          This creates a sample frame (test.frm) file that is used in
 *          BCDEMO 4 and 5. The messages are first created with the BuBCX
 *          message constructors. Their handles are stored in the array
 *          (msgs). A ptr to this array and a minor frame time is passed
 *          into BuBCXMinorFrm. The MinorFrm handle and a filename is passed
 *          into BuBCStoreMinor (saving the minor frame to a file).
