Hi, I don't have a code to show you, what I need are references or algorithms so that I'm in a right track. By the way, thanks for introducing me the array or arrays. Now I can continue my script. Now I want to delete a line from a file. Line being the strings I got/saved to/from array of arrays. This website tells me I have to open my file and create a new file and put my changes to the new file. http://www.rocketaware.com/perl/perlfaq5/How_do_I_change_one_line_in_a_fi.htm So here's what I have in mind, or questions on what should I do? -create a new blank file -open my existing file where it is full of strings with spaces, \n...etc. -where do I make my changes? -how will all the strings from existing file gets copied to new file? -will I need to save all the existing file strings to array of array or just array? what will be my separator? -then when do I do the copying to new file? Before of after deletion of strings from my array of arrays? -when or where can I do the deletion? Sorry about all the questions? I just can't start coding this if I don't know what to do. Please feel free to tell me websites or which perldoc I would be needing to research on. Thanks.
