Windows Unit - What's it good for ?

I have looked in all the indexes and through all the helpfiles, but I
can't find any reference to the Windows unit which Delphi always adds
as to the "Uses" line.

Is there anybody who have the knowledge to answer me ?

It is probably because the Windows unit does not really exist.
"Windows" in this case is an alias to multiple other units.
Wintype and Winprocs I believe (off the top of my head).  So
the Windows unit would be documented in the Wintype and
Winprocs units.

Delphi 2 introduced this new alias technique for units.
Somewhere in the Project|Options menu you can see what unit
aliases you really have.

This unit declares a lot of  data types you need for programming. In
fact this unit is the interface to the Windows-API with all procedures
and data types declared in it.
You may get your project to work without using any procedure, but a
lot of data types are common to the API and the VCL, so they are
declared there.

If you want to test it, just remove the unit from the uses clause and
watch how far you come.

Uhhh, just forgot. It declares a lot of constants, too.

Hope this helps

        In 2.0 WINDOWS is the rough equivalent of WINPROCS and WINTYPES combined.

Actually, it's the other way around. In D2, there is a single unit,
Windows. Delphi defines the aliases, WinTypes and WinProcs to be
equivalent to Windows, for backward compatibility. D1 has two separate
units.
