I recently had to do some changes in some Delphi code. Therefore, I have some basics questions:
fx
that is a string variable?I started using OutputDebugString
, but I couldn't get it working with a variable.

In addition to the 2 answers you got about OutputDebugString() and WriteLn(), for debugging there is a better solution: CodeSite from Raize Software (see http://www.raize.com/DevTools/CodeSite/Default.asp ).
If you have Delphi XE, that should already come with an somewhat reduced functionality version of CodeSite.

You can write a wrapper function to take care of the variables passed to OutputDebugString
as it expects a PChar.
Something like:
procedure DebugMsg(const Msg: String);
begin
OutputDebugString(PChar(Msg))
end;
There is a useful reference for debugging techniques here.
And if your Delphi is a bit rusty there's the ever useful Delphi Basics site. I use it a lot :)

If you have a console application, just use write() and writeln() global functions. If you have a GUI application and want to create a separate console windows, things go tricky (this article will guide you through the process, though it's in C++).
