Hello,

Here's some strange behaviour... it outputs

0 0
0 0
0 50

In fact this is GOOD if base index of parametrised arrays is always 0, but in my previous "array of question" you've said I must use low() and high(). So, what to assume?

procedure aaa(var a: array of Integer);
begin
writeln(low(a):10,high(a):10);
end;
var
        aa: array [0..50] of Integer;
begin
aaa(aa[0]);
aaa(aa[40]);
writeln(low(aa):10,high(aa):10);
end.

Best regards,
Aleksey

Always use low and high. They are evaluated at compile time if possible, so you will not lose any speed and you will always get the correct results.

Shouldn't this be rejected? Passing an integer as an "array of integer"??

open arrays start always with 0. But using low() and high() is the recommended way

No, this is also support by delphi/tp7. It is passed as 'array[0..0] of integer'

I know, but you shouldn't say this, because people will start using 0 (even though low(a) will be replaced by "0" at compile time and as such is just as fast as using "0") and then start reporting bugs if for some reason this changes somewhere in the future for a certain kind of array :)

In that case, there is no problem :)
