Append numbers at same position in strings


Let given three list:
list1 = [1,2,3,4,5,6,7,8,9]
list2 = [10,11,12,13,14,15,16,17,18]
list3 = [19,20,21,22,23,24,25,26,27]
Append numbers at same position in strings.
The result should be:
list = [11019,21120,31221,41322,51423,61524,71625,81726,91827]

Append numbers at same position in strings is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

var
	i: integer;
	{ Indices were chosen to ease up initialization in main block. }
	list0: array[1..9] of wholeNumber;
	list1: array[10..18] of wholeNumber;
	list2: array[19..27] of wholeNumber;

{ Returns the number of digits necessary to express as decimal. }
function digitCount(i: wholeNumber): wholeNumber;
begin
	{ Instead of an `if` branch you can simply write: }
	i := i + ord(i = 0);
	{ Remember: Argument to `ln` must be positive. }
	digitCount := succ(trunc(ln(i) / ln(10)))
end;

{ Appends two list members in place. }
procedure append(
		{ DI: Destination Index; SI: Source Index. }
		var destination: array[diMin..diMax: integer] of wholeNumber;
		source: array[siMin..siMax: integer] of wholeNumber
	);
var
	i, n: integer;
begin
	{ Determine maximum index range. }
	i := diMax - diMin;
	if (siMax - siMin) < i then
	begin
		i := siMax - siMin
	end;
	
	{ NB: In Pascal `for`-loop-limits are evaluation exactly once only. }
	for i := 0 to i do
	begin
		{ In Extended Pascal (ISO 10206) you could actually simply write: }
		{ … := destination[diMin + i] * 10 pow digitCount(source[siMin + i]) }
		for n := 1 to digitCount(source[siMin + i]) do

			destination[diMin + i] := destination[diMin + i] * 10
