When functions (IO Flag set to multiple functions) are brought up from a lower level model, a single net can produce many sub functions (threads) dependent on Function definitions, Mission phases, Classes, States, Design effects and hierarchy depth of the lower level model(s). The above Tokens {*-$X*} give the order in which the analyst wants the function to be described at the local level (no Hiearchy) and at the top (on Assemblies).
There are 4 variations of this Function Options dependent on Past eXpress Versions eXpress Classic, eXpress 5.11, eXpress 5.11 short, eXpress 5.12, and an additional Cusomizable User-Defined variation. These can be reviewed in the window "Output Function Naming Method". eXpress 5.12 is the default if the Analyst does not change it.
