Hand In Assignment

You should have two script files. Create a zip file containing these files and upload the zip file to me, as binary. Do not create a .rar file.

You then have a choice for submitting the file.

• If you are logged onto ocelot, use my uploading program to upload the file. Enter this command at the command prompt: ~downeyt/cs/public/webftp/webftp.pl
• If you are using winscp, then download the zip file to your computer; then, upload the file to me: Submitting Homework Online.

When you are asked for a username and password, use your webmail username with the password that I sent to you. Upload the file as binary. If you upload as text, nothing will be uploaded. Check that the size of the uploaded file is correct.
