Define Parameters
Within the properties of an operation, Activity or Interaction, you can define parameters to control how that object and its subordinate objects behave.
The order or sequence of the parameters in the object properties is reproduced in code. You can set and manage the order using facilities available within the 'Parameter' tab of the object 'Features' dialog.
