I meant ord(High(TMyType)) - ord(Low(TMyType))+1
sorry... :)
but bare in mind that if you initialize them with random numbers you might
face problems

Subject: RE: [delphi-en] Re: getting enumerated count
Your suggestion of " Using "High(TMyType) - Low(TMyType) + 1" to get the
count for the following
types will work without any problem" and will show an error "operator not
applicable to this operand type"
This would however work well:
ord(High(TMyType)) - ord(Low(TMyType))+1
thanks for all the suggestions

You should study the use of enumerated types well before implementing

sequential ord will raise no problem
Using "High(TMyType) - Low(TMyType) + 1" to get the count for the following
types will work without any problem
TMyType = (enum1, enum2, enum3) or
TMyType = (enum1 = 0, enum2 = 1, enum3 = 2) or
TMyType = (enum1 = 123, enum2 = 124, enum3 = 125)
If you are obliged to use a type similar to
(myConst1, myConst2, myConst3= 99, myConst4, myConst5 = 666)
I suggest you define their total number in another constant, those are never
going to change at run time, the only way they can be modified is by the
developper at design time.
This might not be the best of solutions but it would work

Good pick. Anyway, we're just discussing other
possibilities here. The (myConst1, myConst2, myConst3
= 99, myConst4, myConst5 = 666) construct was just
borrowed from C++ to maintain code transparency
between the 2 languages. IIRC, it was introduced in
Delphi 6.
