Unterschiede zwischen Konstanten-Deklaration?

[himitsu]

Zitat:

CTRL_DRIVE: Byte = $0D;

typisierte Konstanten sind keine "echten" Konstanten,
sondern nur schreibgeschützte Variablen.

CASE verlangt aber "echte" Konstanten.


Dieses sind "echte" Konstanten:

Code:

const
  { Amp Drive }
  CTRL_DRIVE       = $0D; // $00 to $7E

  { Amp Toogle Controls (avail. depends on model!) }
  CTRL_DRIVE_ONOFF = $1A; // $00 (off), $40 (on)
  CTRL_DIST_ONOFF  = $19; // $00 (off), $40 (on)

oder

Code:

const
  { Amp Drive }
  CTRL_DRIVE       = Byte($0D); // $00 to $7E

  { Amp Toogle Controls (avail. depends on model!) }
  CTRL_DRIVE_ONOFF = Byte($1A); // $00 (off), $40 (on)
  CTRL_DIST_ONOFF  = Byte($19); // $00 (off), $40 (on)
