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:
Show quoted text 16 lines
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:
Show quoted text 23 lines

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.
