I'm writing C++ code in OPNET Modeler. I try to simulate my scenario in debugger mode & I need to trace the function that I wrote it. I need to show print statements which I put it in my code.

I used in debugger mode: ***ltr function_name()*** then ***c***

But the result looks like:

Type 'help' for Command Summary


ODB> ltr enqueue_packet()
Added trace #0: trace on label (enqueue_packet())

ODB> c

I need to show the print statements in my code. Where it has to be appeared? Is there any step before run the simulation to insure that OPNET debugger using Visual Studio & go through my code??
