*blink* Did I write that?
Had to check my outbox and I guess I did. I meant:
Which usually means it's not a peice of code. But it clearly is.

(ie when you try to "run to here" where there isn't code, it
won't let you.)

Or something :)

Ok. 16c54. No interrupts that I know of. Just wdt which is turned
off.  Instead of stepping over the long parts of code, I modified
the values so they wouldn't loop 1f times, but only once.

I've tried this. Set it up, run/debug/animate, and watch all the
numbers do what they should... But again, instead of leaving
everything set for the full display time, I shortened it so it
wouldn't loop as much. Everything appeared to be normal.

The only thing that made it output anything other than 0000, was
seting up the values to 7777,and removing the bcd packing
routine. So it would appear my problem lies there... it appears
to work when I single step. Can anyone see anything wrong with
this bit:

        swapf   digit2,w        ;put tens place into high nibble
        iorwf   digit1,w        ;ior ones place into low nibble.
        movwf   DSPbcdLow

        swapf   digit4,w        ;put thous into high nibble
        iorwf   digit3,w        ;ior hunds into low nibble.
        movwf   DSPbcdHigh

?

Punch? How about invoking enough precise knowledge to poke a hole
in it?:)
