Thread question...

Is there a way to tell whether a procedure is being called from inside
a thread?

Thanks,

Well, all code runs in threads, but assuming you want to distinguish between
the main thread and some secondary thread, you should be able to do that
with

if GetCurrentThreadId <> MainThreadId then
writeln('in secondary thread')
else
writeln('in main thread');

Perfect! That is exactly what I needed. :-)
