Hello.
I'm trying to use such a code:
type
  TVar = object
      param1, param2:string;
      ....
  end;
TVarList = object
      Items:array of TVar;
      count:cardinal;
      .....
  end;
In Delphi  and FPC it works fine, but in GPC i get an error
45: warning: missing string capacity -- assuming 255
49: error: syntax error before `of'
Is it possible to use dynamic arrays in gpc?
See section [6.2.11.5 EPÂ’s Schema Types including Â‘StringÂ’] of the gpc manual.

ISO 10206 Extended Pascal feature.

type
	RealArray (n: Integer) = array [1 .. n] of Real;
	Matrix (n, m: PositiveInteger) = array [1 .. n, 1 .. m] of Integer;

The type Â‘RealArrayÂ’ in this example is called a Schema with the discriminant Â‘nÂ’.
To declare a variable of such a type, write:

var
	Foo: RealArray (42);
