The first step is to ensure that you have added the course locker. This is done by the following command at your Athena prompt.

athena% add 13.021

To skip this step, all you have to do is put the command add 13.021 in a file called .environment in your Athena home directory.

Make sure you are running on an SGI platform before issuing the following command. This will open the current version of Amass.

athena% /mit/13.021/programs/amass

Be sure not to put an ampersand, "&", after the command, as Amass requires the use of your xterm as a command interface. At this point Amass should open and display the default structure, which spells 'Amass' in cylinders and spheres. In the xterm you opened Amass from, a few status lines should appear. At this point, you may change views, or enter your own structure.
