[fpc-pascal]Problems with "Write" and/or ANSI-Emulation from fpc

[Martin]

hello...

i have problems with "Write" and/or ANSI-Emulation from fpc.
as first please take a look at my testing source:

----CUT------------CUT------------CUT------------CUT------------CUT------------CUT------
uses crt;
var 
  line  : ansistring;
  i     : byte;
begin
  writeln(#027,'[2J');		// ansi-sequence - clear screen
  line := '1234567890abcdef';
  for i:= 1 to length(line) do begin
    write (#027, '[s');         // ansi-sequence - position save 
    write ('',ord(line[i]),''); // ansi-sequence - write data 
    write (#027, '[u');         // ansi-sequence - position restore 
    write (#027, '[4C');        // ansi-sequence - move cursor 4 tokens to the right 
  end;
end.
----CUT------------CUT------------CUT------------CUT------------CUT------------CUT------


the output of the program is exactly:
---------------------------------------------------------------------------
49  50  51  52  53  54  55  56  57  48  97
98  99  100 101 102
---------------------------------------------------------------------------

but why ? normaly the output must be:
---------------------------------------------------------------------------
49  50  51  52  53  54  55  56  57  48  97  98  99  100 101 102
---------------------------------------------------------------------------

has fpc an own ansi emulation in write/writlen procedures ?
if so, there is an bug in the ansi-code sequence/s "ESC[s" and/or "ESC[u".

on the standard	linux console with the shell-command echo the output is 100% ok.

can you help me to fix this problem ?
