Hello I am writing a script (skill) which allow to draw IO frames from a list of cells(dbCreate Inst).I have some problems: 1. When the user chooses to create a cell that already exists in the library, I have to write a warning message to ask the user if he want to overwrite the cell. So I need to have the answer of the user, how can I do it? Who can I read the answer from the CIW? 2. The number of cells that I use to draw the frame is very important so can I group some cells in the same cell to reduce there number. For example I have 7 different cells of routing metals, for each of them I use dbCreateInst, can I group all this cells in only one? 3. How can I order the element of a list from a bigger to the smaller? A=¡¦(8 2 7 9 1) „»? A=¡¦(1 2 7 8 9) Could you please help me? Thanks
