Enumerations are also known as lookup, or combo.
Basically a closed set of string values, that can be selected as input for a method.
To use enumerations in Driver Builder, open the Driver page of the Project entity in Workspace (the root entity)
In Metadata, enter between the DriverCompilationMetadata elements:
<Enumeration Name="Name of lookup you want to implement">
<Member Name="lookup value 1"/>
<Member Name="lookup value 2"/>
</Enumeration>
Save this change.
Now you can go to a driver function, add a string variable as interface, and mark it as enum.
You can treat this variable internally as a string, but the only values that will be accepted to it when calling the function will be a the enumeration values.
