Talk:Character and string types

Doesn't ANSIChar contain an ANSI character instead of ASCII? I.e. it is codepage dependent but can contain byte values 0..255?

This is the information of the official FPC documentation. I will do additional research.

Yes, I suspect the official FPC documentation is wrong/incomplete ;)

BTW: thanks for writing this page - it's very helpful!

Thanks for your positive feedback. In fact, it is ANSI. Although the official Free Pascal documentation states that a char contains an ASCII character, is is stored as a byte to use extended ASCII or ANSI.

Is the sentence in Character_and_string_types#Array_of_Char, delivers: a b c d #0 since arrays are filled with null-bytes in Free Pascal correct?!

I've tested (Lazarus 1.2.2 r44758 FPC 2.6.4 i386-win32-win32/win64 and Lazarus 1.3 r45097M FPC 2.7.1 i386-win32-win32/win64 on Win7)

procedure TForm1.Button1Click(Sender: TObject);
type
  TOldString4 = array[0..4] of char;
var
  aOldString4: TOldString4;
begin
  aOldString4[0] := 'a';
  aOldString4[1] := 'b';
  aOldString4[2] := 'c';
  aOldString4[3] := 'd';
  writeln('['+aOldString4[4]+']');
  Caption:=IntToStr(ord(aOldString4[4]));
end;

I got different results, but not #0 for aOldString4[4]. So, do I have to update the facts or do I missunderstood the statement?
