COMPILING AND LINKING
---------------------
Compile the sample program in Clipper and link using Clipper, Extend,
and the appropriate version of the Protection Plus library according to
your compiler.

SUGGESTIONS:
-----------
Read over the sample.prg file, compile, and copy the exe file to a
floppy to protect.  Run the PROPLUS.EXE host program and experiment with
how to protect the disk.  Run the sample program, and experiment with
the function names, your DOS date, etc.  You can copy the EXE file and
the control file back to your hard drive after protecting it on the
floppy.
