Delphi Applications without Forms?

You bet! First, select File|New Project and choose "CRT Application" from the Browse Gallery dialog. This will provide you with a project that is still a Windows program, but WriteLn, ReadLn will be allowed in a Window but work like they did in DOS. If you wish, you can remove the WinCrt unit from the uses statement (if no user input/output is required, but is nice for debugging).

I've done this before just to see how small an app can be and I've been able to create a simple EXE (it just beeps) that is only 3200 bytes or so in size! Try to do that in C++ these days!

BTW, these "formless" apps are still Windows applications, so they can still call the Windows API routines. You'll just need to add WinProcs, WinTypes to your uses clause. You'll probably also want to add SysUtils and any other unit you find yourself needing.
