Title: convert an Integer to an octal number?
function IntToOct(Value: Longint; digits: Integer): string;
var
rest: Longint;
oct: string;
i: Integer;
begin
oct := '';
while Value 0 do
begin
rest := Value mod 8;
Value := Value div 8;
oct := IntToStr(rest) + oct;
end;
for i := Length(oct) + 1 to digits do
oct := '0' + oct;
Result := oct;
end;
