 I want to exclude the first value of this enumerated type type TEnum = (val0, val1, val2, val3, val4);  in order to make this array TBValues: array [low(TEnum)..High(TEnum)] of boolean;  contains only the last n-1 values (in this case n=5). I tried this: TBValues: array [low(TEnum)+1..High(TEnum)] of boolean;  but I guess arithmetic operations are not allowed in this case because I'm getting this compiler error E2010 Incompatible types: 'Int64' and 'TEnum' How to do this?
