Mike, IIRC, mm_start is the beginning of the heap. When the system or a user program requests memory (new in C++ or malloc/calloc in C) the memory is taken from this block (from mm_start to the end of memory) What might be confusing is how the (...)

Dear Members, I managed to use NQC MONITOR command to watch TIMERs in my SCOUT using the predefined SCOUT events (EVENT_TIMER_0). However, I failed with my Spybotics and RCX 2.0.
