The sample "C" program can be used to copy or format diskettes.
However, the Dynamic Load Library (DLL) that it uses (SABDU001.DLL)
has a restriction.  If the package is not registered the library can
only be loaded by the SABDU.EXE program.  Therefore, to try the
sample program do the following:
       1. Start SABDU.EXE
       2. Minimize SABDU.EXE
       3. Start SAMPLE.EXE

Registering the package removes the need to load SABDU.EXE before
using the DLL.
