Dear

I would like to send a TStringList.text to an external process (kind of stdout)

i have an external process that require to receive datas from stdin

like /home/process1 </tmp/data.txt

I would like my program to send datas inserted into a Tstringlist to this "process1"

I think i should use "Output" but don't know how ?

Do you think this should be answer ?? Is there a better way ?

For i:=0 to List.Count-1 do begin
    writeln(output;list.Strings[i]);
end;

Dear,

Yes. Output already is the default and can be ommited.
