Are you talking about the magic pascalian Initialize and Finalize that
are generated for you but you can't see?

Yes, that is it.

OK, there are instructions for doing that and I have all the source
installed.

the for loop that initializes each unit.

Where does one place a breakpoint in any given VCL unit in order to step
into the Initialize and/or Finalize code for that unit ? As you say, the C++
source code for a unit doesn't show it.

Initialize and Finalize had a priority of 30 if I remember correctly.
PS: You can't build the RTL in BCB6 unless you install the patches.

All patches are installed.

Edward
see if this works.
run the app. ide menu. view debugwindows. modules.
select the exe or whatever module the offending code is in.
in the righ pane. find the namespace @@ finalize method.
click it a couple of times.
put in a breakpoint where you want to stop.
close the exe.

F7 :)
When the RTL is rebuilt with debugging information, stepping into the
program takes you to the RTL source code. The stuff that runs before main.
When I did this, I stepped in to the RTL source and kept stepping until
I hit the for loop that initializes all of the units. Most of the code
up to this point was in C. Stepping through the for loop took me to
assembly land.
From what I remember, there wasn't a good way to break in Initialize
and Finalize for a particular unit. Although once you step through
initialization loop and discover where the code jumps to during the
init, you could put a breakpoint in the assembly code.
