Add code before initialization of units in Delphi

Question

Is there a place where I can add code that will be executed before unit initialization?

The reason I want to do this is I need to change the DecimalSeparator, this h

Answer 1

A word of warning here.

I've got an application running on the desktop of a logged in user and IN THE MIDDLE of testing the app the DecimalSeparator changed for me, without me restarting the application.

I used to set the

DecimalSeparator := '.'; 

once in the FormCreate() code, but that seems not the be enough. So now I set it once every time before I use my FormatFloat() function (used only in one place in my application).

I do not know WHY this happens, but probably there are some system-wide parameter changes happening, that reset the char to ',' on my system.

The best way to avoid this is probably to set the decimal separator in windows configuration to '.' to avoid strange problems...
