Hello,
I am trying to find where WriteLn is declared; but, apparently,
WriteLn is among the select few that Lazarus will ignore 'Find
Declaration' requests --at least that's how it behaves (latest Lazarus
stable) on my side.
My ultimate goal, after finding where it is declared, is to locally
modify that part of the sources so that (instead of writing to the
console) it will use a global callback to display whatever WriteLn'ed
in a TMemo.
Or, is there already an alternative to redirect console output to the
running GUI?

There was already a discussion on this maillist - try to search
"[fpc-devel] StdOut capture for FPC RTL"
It is possible to create pipe, replace TextRec(output).Handle with pipe
handle and rewrite() that output.
Gui thread just reads from the read end of the pipe and updates via
Syncronize() whatever you want (memo, or even synedit).
But you need to rewrite output for every thread you start later.

Anton
