Since FPC (Free Pascal compiler) version 3.2.0., the dynamic array concatenation operator <code>+</code> is available, provided <code>{$modeSwitch arrayOperators+}</code> (which is enabled by default in <code>{$mode Delphi}</code>).
<syntaxhighlight lang="pascal"> array2 := array0 + array1</syntaxhighlight>
Alternatively, one could use <code>concat()</code> which is independent of above modeswitch and mode. Neither option requires the use of any libraries.:
<syntaxhighlight lang="pascal"> array2 := concat(array0, array1);</syntaxhighlight>
A more complete example:
<syntaxhighlight lang="pascal">
Program arrayConcat;
{$mode delphi}
type
TDynArr = array of integer;
var
i: integer;
arr1, arr2, arrSum : TDynArr;
begin
arr1 := [1, 2, 3];
arr2 := [4, 5, 6];
arrSum := arr1 + arr2;
for i in arrSum do
write(i, ' ');
writeln;
end.
