  You can declare your own enum like this:
  

  export enum Size
  {
      annotation { "Name" : "Small" }
      SMALL,
      annotation { "Name" : "Medium" }
      MEDIUM,
      annotation { "Name" : "Large" }
      LARGE
  }
  
  annotation { "Feature Type Name" : "My Feature" }
  export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
      precondition
      {
          annotation { "Name" : "Size" }
          definition.size is Size;
      }
      {
      }, { /* default parameters */ });

  Thank, Ilya. I guess what's confusing me is the use of the globals, in your case SMALL, MEDIUM, and LARGE. Where do those get defined, and kind of data should they be?

  Sorry, reading up on enum objects here, and I think I understand. It's a really strange construct as I understand it. Apparently the all-caps assignment is interpreted as a string, but is also accessible as if it were a map key. It's like a map where the keys and values are identical. I wonder why it works this way.

  SMALL, MEDIUM, and LARGE are not globals -- they are enumeration values defined right inside the enum declaration (see https://en.wikipedia.org/wiki/Enumerated_type)
  Basically the declaration
  

  export enum Size
  {
      REALLY_SMALL,
      MEDIUM,
      TRULY_HUGE
  }

  defines a new enum type Size and says that a value of type Size may be one of three possible values: Size.REALLY_SMALL, Size.MEDIUM and Size.TRULY_HUGE.  See also https://cad.onshape.com/FsDoc/values.html#enumerations for specific info on how enums work "underneath" in FeatureScript .
