A Control File defines all the files used by an individual version of a simulation together
with data that controls the way the simulation progresses and is used by the simulation
manager. Each version of a simulation will have its own control file. For example, changing
the original version to the Assessment Version involved creating a separate control file that,
besides the normal participant reporting pack, defined the assessors reporting pack. As
illustrated to the right, when the simulation is run the Simulation Manager displays a list of
versions for the user to select the version that they wish to use. Here the menu shows versions
in ascending complexity (standard, progressive and compleat), for education and in two
languages.
