We already have zero based strings in 3.0.0 if {$ZeroBasedStrings On} is
used (it's a local switch). It works with Ansi-, Wide- and
UnicodeString, but not with ShortString.
The following example will print
=== output begin ===
l
o
=== output end ===
=== code begin ===
program tzerostr;
{$H+}
var
s: String;
begin
s := 'Hello World';
Writeln(s[4]);
{$ZeroBasedStrings On}
Writeln(s[4]);
end.
=== code end ===

Sven
