Hi Seyed, >> Sorry that if my questions are too ...; I'm a beginner at Jess,
Never apologize for wanting to learn. We all started our studies knowing nothing. :-) Suffice it to say that what you have coded isn't going to work, but there are many many ways to do what you describe. I'm attaching a short Jess script that does what you want while utilizing certain key features of Jess. It is only one of many possible solutions. Though it is missing good error-trapping code, the script does give an example of global-variables, local variables, functions, flow-control, I/O, asserting and modifying facts, and various conditional elements including the "accumulate" CE, as well as how to structure your code. It is sufficiently complex to give you some additional points of study, and it builds on my reply to your last question. By the way, have you read this yet? http://www.jessrules.com/jess/zen.shtml Try the attached CLP file and study its comments. If you have more questions, feel free to ask.
