*System Variables* are built-in operands with useful values. To avoid confusion with other words, they begin with a \$. Descriptions of the CSE system variables follow. Capitalization shown need not be matched. Most system variables change during a simulation run, resulting in the *variations* shown; they cannot be used where the context will not accept variation at least this fast. (The [Input Data Section](#input-data) gives the *variability*, or maximum acceptable variation, for each object member.)
