My ultimate goal, after finding where it is declared, is to locally

a TMemo.
There is no source of writeln, it is split up into various calls by the
compiler. However in the end those writeln routines write a string, and that
routine can be redirected.
Have a look at fpc/packages/streamio.pp
Running assignstream() on "output" would redirect all normal writeln output
to the stream that is the second parameter.
StreamIO isn't, unfortunately, good enough for me. I need to see WriteLn
output in real-time, not when the application (or the called function) ends.
