              READ.ME for SCOPE implementation
              ********************************


This package includes the following files:
******************************************

        read.me         you are just reading it
        test.prg        small test program to show the functionality
        scope.ch        just for the translation for usage of COMMANDs
        makefile.mak    for the usage of NMAKE (make utility)
        scope.def       this is the tricky file (do not delete it)
        scope.prg       this is the SCOPE <g>
        makedll.bat     for all of you who do not have NMAKE
        project.xpj     project file for the sample
        test.dbf        sample table
        cl.bat          MAKE batch for Clipper/Comix version



What leaves to tell?
********************

1. to build the project, please run
        MakeDLL
   or
        nMake -f makefile.mak
   first and then
        PBuild
   You should have a TEST.EXE then!

2. you can run TEST.EXE with or without a parameter:
        TEST            starts the app with NTX DBE
        TEST CDX        runs the app with CDX DBE; the Clipper app will
                        run as CDX version anyway

3. if you try to run the app against the Clipper app, you need to
   make sure that the Clipper app built the CDX !!!

4. why does it work, but I did not change any code of my app, just
   linked a LIB?

   Have a look in SCOPE.DEF file. This shows a way, how you can
   overload every Xbase++ function, which means you do replace the
   origianal function of the Xbase++ runtime, just redirect the call
   to the replacement and there you can even use the original call.
   This works with eg. with the function Version()

        VERSION      = _VERSION

   which results in the function _Version() of the DLL first
   even when you call Version() in your app (Version() is mapped to
   _Version() in your DLL; just call the app in the debugger to see
   what is happening exactly).

   VERY IMPORTANT NOTE: explaining and showing this feature to you
                        makes support of Xbase++ very difficult. So,
                        please do overload Version() when you use
                        this feature!!! Otherwise we can't do a good
                        support, because you overloaded a
                        functionality. THANKS!

Have fun with it,
