... files.¹

The lab system encourages you to use a floppy disk if you want to save your files. There is no permanent storage for students on the 6.001 lab system. You can also transfer your files to your Athena directory over the network. See the 6.001 web page on problem sets for information on how to transfer files to and from the lab: don't use FTP!

... sets.²

If you're running Scheme on your own PC and want a little mindless diversion, you can adjust the screen size, position and color. Click on the shield icon at the upper left of the Edwin window to adjust the font and the background color. You can change the foreground color using the command M-x set-foreground-color.
