[fpc-devel] Implicit cast from Char/String to array of Char

[Ondrej Pokorny]

Hello!

Implicit cast from Char/String to array of Char: is this a wanted 
behavior or is it a compiler bug?

(Btw. MODE DELPHI behaves the same).

program Project1;
{$mode objfpc}{$H+}
procedure A(AC: array of Char);
var
   C: Char;
begin
   for C in AC do
     WriteLn(C);
end;

procedure B(AC: array of Integer);
var
   C: Integer;
begin
   for C in AC do
     WriteLn(C);
end;

begin
   A('a');  // no error in FPC (error in Delphi)
   A('ab'); // no error in FPC (error in Delphi)
   B(1);    // error in FPC & Delphi
end.
