TStringList vs. TList

Question

what is the difference in using a standard

type 
  sl: TStringList 

compared to using a generic TList

type 
  sl: TList

        

Answer 1

I'd probably say if you want backwards compatibility use TStringList, and if you want forward compatibility (perhaps the option to change that list of strings to say list of Int64s in the future) then go for TList.
