ABOUT
-----

CLAM is an EMYCIN-type expert system shell supporting backward chaining
with uncertainty and explanations.

Unlike NATIVE, which uses native Prolog syntax for the knowledge,
CLAM uses Definite Clause Grammar (DCG) rules to parse a rule syntax of
its own design.


USE
---

From DOS type:

	c:\> clam

To start up CLAM from the listener, type:

	?- [clam].	% equivalent to consult('clam.pro').
	?- main.

An additional file is BLDRULES.PRO that uses DCG to convert a file of rules
in Prolog syntax into CLAM syntax.  

The commands are: consult, restart, load, list, trace, how, exit

They are entered without the ending period after the > prompt except for 
the load command which does a normal Prolog read(X) to get the file
name.

consult	Starts the consultation

restart	Clears the knowledge base of known facts for rerunning a
	consultation.

load	Loads the knowledge base.  Other commands do not require Prolog
	syntax but this one does.  Use 'car.ckb'. with the ending period.

list	Lists the known facts in a consultation

trace	Sets trace on or off, as in trace on or trace off

how	For example, to get an explanation type:
		how problem is battery

exit	Exits.


PROJECTS
--------

Fix file reader, so it is friendlier, make a general file reader for
	all of the xsip programs.  read_fname(F) or read_fname(F,Ext) 
	where Ext is default extension and maybe even 
	read_fname(Path,F,Ext) where path is a default path if the 
	file isn't found in the current directory.

Get clam to work with nice user interface.

Get bldrules to work with menu ask and multiple option rules in BIRDS.NKB.
