Well, currently gpc support trurly dynamic strings (and arrays) only
via pointers, like:

type
    StrPtrT = ^String;

function blanks(n : integer) : StrPtrT;
var result : StrPtrT;
    i : integer;
begin
    new(result, n);
    for i := 1 to n do
       result[i] := ' ';
    blanks := result;
end;

You may look at the 'stringschemademo.pas' demo program to see
some possibilites offered by gpc strings.
