$FFFF can both be const and not ?

[dormky 2]

const
  TT = $FFFF;
  TTARRAY = [$FFFF];

The second line gets "E1012 Constant expression violates subrange bounds", but it's functionally the same as the first one. Is the compiler just dumb or do I need to write this in another syntax ?

 

The actual use case is an array of const TColor. Thanks 🙂

Despite its name the TTARRAY declaration is a set and not an array, but sets are limited to elements with ordinal 0..255.

Alright, got it. Still cannot work with TColor but it's better then nothing, example :

  // The highlight colors here are defined twice so the compiler doesn't complain.
  YELLOW: TColor = $00BBFF;
  BLUE: TColor = $F0CF89;
  HIGHLIGHT_COLORS: array[0..1] of TColor = ($00BBFF, $F0CF89);

Thanks !

I have no problem to compile it:

 

const
// The highlight colors here are defined twice so the compiler doesn't complain.
  YELLOW = $00BBFF;
  BLUE = $F0CF89;
  HIGHLIGHT_COLORS: array[0..1] of TColor = (YELLOW, BLUE);

You can also compile:

 

const
// The highlight colors here are defined twice so the compiler doesn't complain.
  YELLOW = TColor($00BBFF);
  BLUE = TColor($F0CF89);
  HIGHLIGHT_COLORS: array[0..1] of TColor = (YELLOW, BLUE);
