2-18 Getting Started
Suppose now that you are interested in only one address in the
RESULTS area, say 5C2H. You wish to see how many loops of the
program occur between each write of a random number to this
address. You can enter a trace command that triggers on address
5C2H (since it's the only address of interest), stores only writes to
address 5C2H, and counts the address of the AGAIN label (406H).
For example:
trace after 5c2h
only 5c2h
counting state AGAIN <RETURN>
