Parameter (dictionary item)
For automation interface information about a Parameter, see Parameter (automation interface).
A Parameter is a variable used for transmitting and receiving data. The actual value supplied to a parameter is known as an argument. You can assign a Data Type to a Parameter, which may be a simple type such as long or char, or a structured type such as a Type Definition.
You can create a Parameter through the context menu of an Activity, Event, Exception or Operation.
In addition, you can also create a Parameter by copying an existing Parameter. Modeler copies the Parameter's links. For more information, see Copying items.
You can specify the Type, Mechanism, Name and Default of a Parameter through its Signature, or through the Signature of an owning Activity, Event or Operation. See the following topics for more information.
If an owning item's signature is greater than 200,000 characters, the Parameters' Default values are not included in the signature.
On an Activity Diagram, Input Pins and Output Pins can represent Parameters.
In the Modeler panes, a short-cut symbol on the Parameter's icon indicates that the item is a stub.
* 
The Name of a Parameter cannot contain spaces.
* 
If you select the UML\Parameters folder in the Dictionary pane, the Contents pane displays the following information about each Parameter in the model: Operation (owning if applicable) and Mechanism.
The following sections provide information about how a Parameter is used in the model. For more information about a property, item, model part or diagram, click it.
Properties
In addition to the standard properties, a Parameter has these properties:
Default (Default Value through the automation interface)
Mechanism - 'In', 'Out', or 'In and out'.
Owned by
Owns
Dependency - The Dependency is owned jointly by the Parameter and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.

When a Parameter uses an item as a data type, Modeler creates a special link between the Parameter and the referenced item. You cannot navigate this link through the Links Editor.
