New- Resets all program variables, including initial conditions to their default program settings. These settings should be identical to the program conditions from when the program was first run.

Open- Allows the user to open a previously saved configuration file. These files should be saved with the default extension *.scc.

Save- Allows the user to save the current program configuration in order to revisit the system at a later session.

Start- Enables the simulation’s timer which begins execution of the simulation.

Stop- Disables the simulation’s timer which stops execution of the simulation.

Reset- Resets the particle’s positions and velocities according to those specified in simulation parameters dialog.

Slower- Slows the simulation’s timer which slows execution of the simulation.

Faster- Speeds the simulation’s timer which speeds execution of the simulation.

Fast Forward- Quickly takes data for 100 points and plots it on the screen.

Parameters- Opens the simulation parameters dialog which allows the user to specify the system’s conditions, including the initial position and velocity of each particle.

Help- Opens this here text file!

About- Views the ‘About Spring Chain’ dialog box.
