Hello all,

A while ago in one of the FPC lists I had read that FPC 2.2.0 supports array slices. So I made a program to test this feature:

program Test_Slices;

   procedure Test(C :  array of Integer);
   begin
   end;

var
   A : array of Integer;
   B : array of Integer;

begin
   setLength(A,6);
   Test(A[2..4]); // This works
   setlength(B,6);
// B := A[4..6]  // Compilation error if I uncomment this line
end.

The above code, as it is, compiles without problem. However if I uncomment the last line, I get a compilation error:

Are array slices only supported as arguments to subprograms calls?
I 'm using FPC 2.2.0 on Mac OS X Intel.

Thanks very much in advance,

C.C.
