Getting Started 2-16
The tg (specify simple trigger) command allows you to specify when the
analyzer should begin storing states. For example, suppose you want to
look at the execution of the sample program after the AGAIN label,
and therefore, you would like to begin storing states after the AGAIN
address occurs. To do this you could enter the tg command shown be-
low and display the trace.
