Abaqus - Parameter name assignment

Dear Abaqus  users, I have an issue understanding assigning names to parameters, lets say I want to assign a name of parameter that is so specific to my design how can I do that so I can change that in my parametric study?

As far I can find in abaqus documentation the explanation uses generic parameters as width and length what about other parameters like a diameter of a certain curve or the distance between two lines?
