Well, the DER lets you look for multiple conditions at once. Your program is blowing up, the memory is getting trashed and you don't even know if the hardware is valid - that's where BDM really shines. I don't see where COP let's you do the equivalent of setting a bunch of bits in the DER, so please enlighten us if we're missing it! Mark Chambers P.S. I've read the BDI manual - I don't see it. My manual says the BDI can only set one hardware breakpoint, and stuff like VECTOR CATCH assumes valid memory.
