   2. State: Displays whether the patient is ill, unconscious or dead
   3. Time: The present time and date, in terms of the body clock
   4. Play: Stop or start the clock
   5. Time compression: The slider’s values indicate
      1. Real time
         
      2. 1 minute per second = x 60
      3. 1 hour per second = x 3600
      4. 1 day per second (these may not work well on a slow
      5. 1 week per second computer)
   6. Reset: Reverts all variables’ values to the initial state
2. Menu bar
   1. File: Allows saving and loading of current variables’ values.
   2. Graph: Commands to manipulate the scrolling graphs displayed in the main section of the display.
      1. Rate: Control the timebase of the scrolling graph, in pixels per 50ms.
      2. New Orbit: Create graphs that plot one variable's value against another
      3. Setup: Display a predefined set of graphs
      4. Close all: Close all graphs
   3. Fluids: Select fluids and drugs to administer, which appear as intravenous infusions on the top-left. You can also administer boluses of drugs intravenously or orally
   4. Tools: Various dialog boxes to help with diagnosis of problems
   5. Help: Display help boxes on various aspects of the program
      1. Scenario information: Information on the current setup, including your learning objectives
      2. Physiology help: Details of the physiological model, with explanatory diagrams
      3. Interpreter help: Summary of commands for the interpreter in the console or in scripts
      4. About: Information about the program version, and the current system
3. Tree
   
   1. Values of variables are displayed to the right of their names
   2. Expand or contract branches with the + or – buttons
   3. Right click on a variable to get a menu, or double-click to see info
   4. Use the Display button to show a graph of the variable on the right
4. Graphs
   1. On a scrolling graph, click the name of the variable to see info
   2. Click on the scale above the graph to zoom in or out
   3. Drag in the black graph area to make markings
   4. Right click in the graph to alter the timebase
5. Message pane
   
   1. Messages about events in the simulator are displayed in this box.
      
   2. On a blank line, type expressions and press return to evaluate them
      
      1. Variable paths, from the ‘body’ or ‘environment’ level of the tree (e.g. air.O2, kidney.urine.Osm)
         
      2. Mathematical symbols e.g. + - * / pow(X,Y), sin(X), max(X,Y)
         
      3. Equations to set variables, e.g. blood.K=0.003
