For instance, the programmer cannot write: RULE 0: IF (Temperature IS VERY Cold) THEN (Output IS VERY High) However, the programmer can simply define new sets for "very cold" and "very high".
例如，程序员不可以寫： RULE 0: IF (Temperature IS VERY Cold) THEN (Output IS VERY High) 中譯：規則 0: 若 (氣溫 為 非常 冷) 就 (輸出 為 非常 高) 可是，只要定義新的集合給「非常冷」和「非常高」就可簡單達到目的。
