A reference is a unique text string referring to a node in a model. This text string can then be used as a parameter (窶彗窶, 窶彙窶,窶ｦ) in edge functions.
If e.g., the model contains a parameter which is used in many edge functions, you may create a node with this parameter value and then create a reference to this node. The reference can then be used in all the edge functions. If you want to change the parameter value, you just edit the node value. You may also introduce stochastic parameters in the edge functions by using references to stochastic nodes.
Select a node or a group of nodes. Select 窶廚reate reference...窶 and a dialog box appears where you can specify the unique text strings.
Show reference窶ｦ
Shows a list of all references in the active model. You can use this to find out which nodes the references are attached to, and search for edges which use these references.
