Defining types from other units in Delphi

Var
     A : Array [1..4] of Integer;
     B : Array [1..4] of Integer;

Begin
    A := B;

Won't work as loren-pechtel said here the problem is A and B for me are in different units. So, is there a way to define a type definition from a existing one in another class?

Solution

  • Define type in interface block of some unit and then include that unit via uses clause in other units where you need that type.

    unit A;
interface
type
  TMyArray = array [1..4] of Integer;

...

    When you need to use TMyArray in another unit:

    unit B;
interface
uses A;

...
var x : TMyArray;
