The main advandage of Pascal is that strong typization mekes working whith pointers and dynamic structures very easy. If i need to write my own class for Normal Strings, and for most of functions to work whith it - it is better switch to fpc, or just c++ - it's already written.
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.
