 ; Correct output is two stops. A and B differ between them, the addresses differ, and the

+; a program is handed the pointers as it finds them - but it is not this program's to

+; to sit. The recorded output had to be taken again four times in one day's work, every
+; time for a value nothing should ever depend on.

+; A demonstration of what the registers were should show registers somebody chose. Then
+; every line of it is being asserted rather than merely observed.
+;
+; DP3 is deliberately still the system's. It is where the program was entered, which is the
+; one thing here worth seeing that this program did not choose, and it is steady because it
