[fpc-pascal] Question about Deleting elements in Dynamic Array

[Bihar Anwar]

I've tried to use Move() instead of Copy(). Any objection with the following code?

var
  a: array of string;

SetLength(a, 5);
a[0] := 'aa'; a[1] := 'bb'; a[2] := 'cc'; a[3] := 'dd'; a[4] := 'ee';

System.Move(a[3], a[0], 2 * SizeOf(string) );    // instead of  a := Copy(a, 3, 2);
SetLength(a, 2);

Copy() (from the existing dynamic array).
