The program uses the Delphi standard "TList" component to collect the numbers. Since it normally holds pointers, the integers are recast as pointers. The TList components provides a quick sort routine that is customized by providing your own compare routine.

You could also apply res:=unique(res), anywhere/8 ways: new line in 3 places, or inline (two ways each) on either existing assignment, or as a replacement for the sort(), which would reduce the length by 1 (the duplicate 36) and yield a total of 654.

The task description seems to dictate how a program is supposed to solve
this, rather than merely provide a procedure that determines the
solution. XPL0 doesn't have a built-in list capability like Python. A
simple substitute is to treat the lists as arrays. A complication is that
list[3] is shorter than the others, which is adjusted here. XPL0 also doesn't
have a built-in sort routine (although one is provided in its library).
Displaying a small number of sorted items is easily done with a few lines
of code.
<syntaxhighlight lang="XPL0">int List(3+1), Min, I, J, S, MI, MJ;
def Inf = -1>>1;
[List(1):= [3,4,34,25,9,12,36,56,36];

List(3):= [75,121,75,144,35,16,46,35,Inf];
loop [Min:= Inf;
for I:= 1 to 3 do
for J:= 0 to 8 do
[S:= sqrt(List(I,J));
if S*S = List(I,J) then
if List(I,J) <= Min then
[Min:= List(I,J); MI:= I; MJ:= J];
];
if Min = Inf then quit;
IntOut(0, Min); ChOut(0, ^ );
List(MI, MJ):= Inf;
];
