(* This example was written at as a console app in delphi 6 if you want to use
it in Turbo Pascal All you have to do is delete {$APPTYPE CONSOLE}
and underneath Uses change SysUtils to Crt *)
program Bubble;

uses

Var
Ary : array[1..10] of byte;
InnerLoop : integer;
Outerloop : integer;
temp : integer; {The reason I use this temp is so I can swap the value in the
array over. If I had the following:
x := y;
y := x; y will just wont get y because you assigned y to x
and variables can only hold one Value :)
So by using the Temp variable I can swap them over
temp := x;
x := y;
y := temp;}
begin
randomize;
for innerloop := 1 to 10 do
begin
ary[innerloop] := Random(100);
writeln(ary[innerloop]);
end; {assign some numbers to the array}
{start sorting the array}
for outerloop := 1 to 10 do
begin
for innerloop := outerloop to 10 do
begin
if ary[outerloop] > ary[innerloop] {To displa in decending order change
> to <}
then begin
temp := ary[outerloop]; {enables me to swap the values over}
ary[outerloop] := ary[innerloop]; {make the lowest value higher up in the
the array}
ary[innerloop] := temp;
end;{end IF}
end; {end inner loop}
end;{end outer loop}
