I have a question about writing Excel files using Win32::OLE. I need to open a bunch of files and write to them from time to time in a table form. Unfortunately, I would not remember which line I should go to (the row number) unless using an array with the current line stored. Could someone help me with a method to let the writing automatically change lines as write "\n" to a text file? Besides, where I may get the API of all the possible functions of Win32::OLE?
