请问PRO/II中 Arrays下面的IS( )和IX ( )这两个数组代表 ...? 英文学的不好 IS( ) An array of elements used as indices of DO loops for stepping through a series of streams in the order defined in the Stream Sequence table. The first index of the array is zero and hence the array indices range from 0..Array size -1. The default size is 10. IX( ) An array of integer values. The first index of the array is zero and hence the array indices range from 0..Array size - 1. The default size is 200. 这两个的解释我看不懂,请高手指教。谢谢!查看更多1个回答 . 2人已关注
