Hi all.

D2007.

What is the proper way to get notification for debugger step (F7/F8)?

I've found Erik's advice:

>> What notifier should I use to trap the right notification
>> when the process is stopped and goes into debug mode? 

> Try IOTAThreadNotifier.ThreadNotify. 

but I have no idea where and how I can install that notifier.

TIA.

You have to call IOTAThread50.AddNotifier.  You can get the IOTAThread 
interface using a process notifier and watching for ThreadCreated:

   IOTAProcessNotifier = interface(IOTANotifier)
     ['{34B2E2D6-E36F-11D1-AB0E-00C04FB16FB3}']
     { Called when a Thread is created }
     procedure ThreadCreated(const Thread: IOTAThread);
     { Called when a Thread is Destroyed }
     procedure ThreadDestroyed(const Thread: IOTAThread);
     { Called when a Process module is added }
     procedure ProcessModuleCreated(const ProcessModule: IOTAProcessModule);
     { Called when a Process module is deleted }
     procedure ProcessModuleDestroyed(const ProcessModule: IOTAProcessModule);
   end;

Or try IOTAProcess60.GetCurrentThread, etc.

You need to walk your way back until you get to a base interface like 
IOTADebuggerServices that is supported by the BorlandIDEServices global 
variable.  You may also have some luck searching the web/newsgroups for 
sample code using IOTAThreadNotifier.

OK, it's clear now.

Since then I asked I've changed my mind and decided don't respond to
every debugger step.

Thank you anyway.
