For better performance use a dynamic array (Delphi 4+)
var
A :array of integer;
I,N :Integer;
begin
SetLength(A,10);
for I := 1 to 4 do A[i-1] := I;
N := 1;
// Generalised deletion of an index held in N
if N<(Length(A)-1) then move(A[N+1],A[N],SizeOf(A[0])*Length(A)-(N+1));
SetLength(A,length(A)-1);
end;
or something like that...
