The dump labelled the status register "S", which reads as Stack to anybody sensible - and the Stack Pointer was the one register it did not show, so there was nothing to contradict the guess. It is written "status" now, and followed by the bits that are up, because a dump that makes you look the number up is only half a dump. The Stack Pointer is not in the frame, since the frame is where the Stack Pointer is. What the program had is fourteen bytes above it, that being what entering an interrupt puts down, so it is worked out and shown. Apps/Break.asm takes its second stop inside a subroutine, so the recorded output shows the Stack Pointer at FFFF and then at FFF5: a difference of ten, which is the size of a CALL frame. That checks the value is derived rather than constant, which the previous version could not have told you. Reported by Anachronaut, who read the output and asked why a pointer was two digits long.
