Why is Url an undeclared identifier here?

[dummzeuch 1392]

Unit bla;

interface

type
  TServerParams = record
    Url: string;
    XCoord: Integer;
    YCoord: Integer;
  end;
  TServerParamsArr = array of TServerParams;
const
  ServerParamsArr: TServerParamsArr = (
    (Url: 'https://ows.terrestris.de/osm/service'; // <===
    XCoord: 529850;
    YCoord: 5284850),
    (Url: 'https://geoportal.koblenz.de/geoserver/OEFFENTLICH/ows';
    XCoord: (391000 + 408000) div 2;
    YCoord: (5571000 + 5586000) div 2)
    );

Given the code above, why do I get a compile error at the line marked with // <=== ?

"E2003 Undeclared identifier: 'Url'"

 

This is with Delphi 10.2, just in case that matters.

 

edit: It compiles if I change TServerParamsArray:

type
  TServerParamsArr = array[0..1] of TServerParams;

I believe that "your definition" itself as a "limited elements" = 2, or be a const have "n" elements in your array, and you dont say "how many"

Array constants with no predefined length never were not allowed

In fact they are:

type
  TStringArr = array of string;

const
  cStringArr: TStringArr = ['Hello', 'World'];

Just not with the record element type, because the record constants are not accepted as true constants.

Funny, even after 20 years of Delphiing you can discover something new 🙂

 

Edit: Alas, that's only for compilers with array literals.
