MagicFrisbee (Programmer) 8 Feb 07 17:58 Note that each dimension has its own set of parentheses. All hail the “const” parameters! By Eric Grange / July 28, 2010 Passing parameters as “ const ” is a classic Delphi optimization trick, but the mechanisms behind that “trick” go beyond cargo-cult recipes, and may actually stumble into the “good practice” territory.

Delphi Constant

Free Hi, Let's suppose the following code, which is used as sample, that is to declare a Constant array of record: type TShopItem = record Name: string; Price: currency; end; const Items: array[1.3] of TShopItem = ( (Name: 'Clock'; Price: 20.99), (Name: 'Pencil'; Price: 15.75), (Name: 'Board'; Price: 42.96) ); What if I want to declare a to declare a Constant array of array of record (array of array). How do I declare that?

Delphi Declare Constant Set

Taking the previous classes, now suppose that I have 'groups' of TShopItem's, like: Group 1 (Name: 'Clock'; Price: 20.99) (Name: 'Pencil'; Price: 15.75) Group 2 (Name: 'Board'; Price: 42.96) (Name: 'Eraser'; Price: 2.96) Group 3 (note different length) (Name: 'Paper'; Price: 5.96) (Name: 'Pen'; Price: 2.96) (Name: 'Postits'; Price: 2.96) How do I put all that in a single constant array of array declaration? You cannot because the groups 1, 2 & 3 do not have the same size, so you cannot declare a single array. Or you declare an array of 3x3 and there will be some holes (unused elements) const Items: array[1.3, 1.3] of TShopItem = ( ( (Name: 'Clock'; Price: 20.99), (Name: 'Pencil'; Price: 15.75), (Name: 'Board'; Price: 42.96) ), ( (Name: 'Paper'; Price: 5.96), (Name: 'Pen'; Price: 2.96), (Name: 'Postits'; Price: 2.96) ), ( (Name: 'Clock'; Price: 20.99), (Name: '-'; Price: 0), (Name: '-'; Price: 0) ) ); Select all. A constant for a price?
