and anything that a search for "Perl tutorial" might come up with. Also, you might want to re-read the forum rules, esp. Rule 6.

You shouldn't do students work for them. Instead tell them to look into the modulus operator or other tips, but just writing the code for them is not appropriate. Especially when they demonstrate no effort at all to write such a simple little program.

Ban him/her from the forum for doing students work for them. It should be just as bad a violation, or worse, than posting the schoolwork. But black is white and white is black in this cazy world. Oh well. Smilie
