The WITH - ENDWITH command/clause set is for referencing objects. In your example above, .EventType is both a property and an object, which cannot happen as you have above. You can have a custom property called EventType that can be assigned to both, but it cannot have it at the same time:

this.EventType = 'A'  && Somewhere in code...  Now a property with a char value
...
WITH this
  IF VARTYPE(.EventType) = "C"         && Check that char value is assigned
    DO CASE
      CASE .EventType = 'A'
         .EventType = oMyObjectRef     && Now assigned to an object value
         .EventType.Code = 'S12'
      CASE .EventType = 'B'    && etc.
    ENDCASE
  ELSE
  ENDIF
ENDWITH
