Hi Bruce,

Thanks for the reply; very lucid, as always.

I now understand the issue I'd raised (kind of). What I dont understand yet, although you've touched upon it, is why the animation jumps to the library window whenever it encounters a pause statement. And then doesnt seem to return back to the source window. But, single-stepping seems to work fine.

About the port pins. What you are saying is, I'd have to watch the whole port, and then see the behaviour of the individual pins within; am i right in my understanding?

I must say MCS Plus has really spoilt me; this is one thing about it I miss. But like you said, there seem to be loads of other things in favour of MPLAB that makes the transition worthwhile.

Thanks again.

Anand
