Rob didn't implement trace (other than trace(3)) into the pd source.
If you take a look at my modified interpreter (in the user contributions), 
you'll see that I've got an interactive debugger (for Win32 and Linux) 
using wxEuphoria.  The framework is there so that you could write your 
own, however.  I think it's more usable than the standard Eu trace screen.

I think you mean callbacks.  Rob implemented the source with a limited 
number of callbacks.  I've added a callback mechanism that can dynamically
allocate new callbacks using a few lines of asm, so the number of callbacks
are now unlimited.
