E2193 Slice standard function only allowed as open array argument (Delphi)

Go Up to Error and Warning Messages (Delphi)

An attempt has been made to pass an array slice to a fixed size array. Array slices can only be sent to open array parameters. none

program Produce;

  type
    IntegerArray = array [1..10] OF Integer;

  var
    SliceMe : array [1..200] OF Integer;

  procedure TakesArray(x : IntegerArray);
  begin
  end;

begin TakesArray(SLICE(SliceMe, 5));
end.

In the above example, the error is produced because TakesArray expects a fixed size array.

program Solve;

  type
    IntegerArray = array [1..10] OF Integer;

  var
    SliceMe : array [1..200] OF Integer;

  procedure TakesArray(x : array of Integer);
  begin
  end;

begin TakesArray(SLICE(SliceMe, 5));
end.

In the above example, the error is not produced because TakesArray takes an open array as the parameter.
