I do have a enumated type:
type VALUE is (ABC, DEF, GHI, JKL, MNOP);
Suppose I have a parameter with the value DEF is there a simple way to
get the next value like you can with integers in the way of V2 := V1 + 1
for instance OUT := NEXT( ABC).

Next value: VALUE'Succ (V1).
Previous value: VALUE'Pred (V1).
