摘要: A programmable computer which operates by executing rules, each including a rule name, and optionally: input parameters, set of conditions, actions associated with condition, exception handlers. condition is logical expression evaluates to true or false boolean value, while an action executable statement. An handler contains statements. The includes text entry display means for programming rules. displayed having row text. generates yes/no quadrant into programmer may enter sequence numbers, associate ordered sets individual conditions. Sequence numbers be entered not any define default actions. Upon entering rule, the sequentially rule's evaluating true, executes that then exits rule. If no conditions none will executed, exited. If, during execution detects event, such as missing datum other error, passes name detected event. bearing same execute statements within handler.
