The advantage of enumerated types is strong compiler type checking. Ie no spelling/keying mistakes. If you use the normal convention for enumerated types, .e.g
MyStayus = (msActive, msPending, msEnded ) etc Then you can use a function and RTTI to convert the enumerated type name into a string for display. There is a RTTI function that returns the name of an enumerated type e.g. "msActive", and then your function can strip off the leading lowercase characters.

Why use a set when string work ok? (and I think it's a set) Question: I have seen this quite a bit and apparently it's "good practice" however to me it seems like more work. Example Whats the point in doing this MyStatus = (Active, Pending, Ended, Paused, Deleted, Suspended);); type Something = class name : string; status : MyStatus; end; then example on create or something status := Active; (yes, missed out lots of steps :P) and now if I want to show the status, I have to do something like.. If status = MyStatus(Active) then showmessage('Active'); If status = MyStatus(Pending) then showmessage('Pending'); etc Why go though all that hassle when just doing this is fine status : string; status := 'Active' showmessage(status); so instead of using "MyStatus" types I just use a string - this means when I want to output the status to the user I don't have to try and convert it to string first. So, why do it?
