Delphi Interface

Setting Up Delphi

The Delphi interface is in the runtime/delphi subdirectory. Before you can run this program, you must set-up the Amzi! Logic Server.

You can do this by either:

Put the kw4/workshop directory on your PATH environment variable
or
Copy amzi.cfg, amzi.dll, aosutils.lsx, aodbc.lsx to the directory containing the Delphi code.

Then you need to:

Copy the jig reasoning engine (.xpl) file from the workshop/jigs subdirectory. For the basic jig, this is basic.xpl, for the support jig, this is support.xpl, etc.
Copy the knowledgebase (.kb) file you want to run to the directory containing the Delphi code.

This will let you run the sample as provided. In order to write your own Delphi programs, you need to install the Amzi! Logic Server Component. The Logic Server Component, TLSEngine, is implemented in the Object Pascal unit amzi.pas for 32-bit Delphi. You can use it as an Object Pascal unit by simply including a reference to it in the USES section of your application, or you can install it in the Delphi component library.

It is important to follow the directions carefully when installing amzi.pas as a Delphi component. Delphi must be able to find both amzi.pas and amzi.dll. The directions assume that you set your environment variable PATH to include kw4\workshop. Replace N in the directions with the version of Delphi you are using.

Open Delphi.
Select from the menu 'Component/Install Component�'
Select the 'Into existing package' tab which will by default install into the "Borland User Components" package in the file \borland\delphiN\Lib\dclusrN0.dpk.
Press the button marked 'Browse' next to the 'Unit file name' box.
Select \kw4\runtime\delphi\amzi.pas
Note the search path should now include \kw4\runtime\delphi.
Select 'OK' on the Install Component dialog box.
Select 'Yes' on the 'Package dclusrN0.dpk will be rebuilt' confirmation box.
Select 'OK' on the dialog box informing you that TLSEngine has been added to the package.
You should now see the Amzi! flying squirrel logo in the Additional components.

Note: When embedding KW in Delphi, make sure your jig (.xpl filename) is different from your Delphi .exe file. This is necessary so that KnowledgeWright does not try to use Delphi's .cfg file and vice versa.
