Hello.
I found code in olly that is calling some function.
There are 63 references to that function.
How can I see what was the code history.
It's hard for me to describe it. I'll try this way.

I set breakpoint on one instruction.
How can I see what commands were executed before?
Something opposite to "step over" like "step back".
Is this even possible?

And second question. What is "Trace" and how to use it.

The return points are stored in the stack so You can see where was the function called if You look at it.

And trace will trace and log the execution of the codes from the breakpoint or where You have stopped.

Is there any tutorial on this run trace thing?

I don't know but it is very easy. If You have stopped the program, just click on trace and when You click on Run it will trace the codes.

Open trace will open the trace window.
Run hit trace will start the trace.
