Assigning an Action
Assigning an action tells the analyzer what to do when it has found the
targeted event. If you do not assign an action, the analyzer will look for
the event but do nothing once the event has been encountered.
Assigning an action is a two-step process: first, move an Event button
from the Available Events area on the left to one of the two cells in the
center of the window. Then, right-click on the Event button and assign
an action.

Cell
The center of the
Recording Rules
window is where rules
are defined. To create
a rule, you must drag
an Event button from
the Available Events area on the left to one of the two cells in the center
of the Recording Rules window. The cells in the center control the
duration of the rule: rules created with the Global State Cell are always
enabled, while rules created in the Sequence cell are conditionally
enabled.
The Global State Cell - The Global
State Cell tells the analyzer what
events to look for throughout the entire
recording. The cell is called a "Global
State" because the conditions you
define in the cell are always active.
You can place several events in this
cell. Doing so tells the analyzer to look
for all of the events all of the time. For
example, you could place three events
in this cell and have each cause a
trigger. Such a configuration would read "If any of the events occur,
trigger."
Sequence Cell - Sequence cells are marked with the faint text Drag to
add a new sequence.
The Sequence Cell is
used to create event
sequences. An event
sequence is a chain of
events leading to some
action. For example, "If
x is followed by y and
then by z, trigger."
Events linked in a chain
are looked at
sequentially. Thus, at
any given time, the analyzer is often only be looking for a single event
out of the several that might be in the Sequence cell.
To activate an Event button, drag it to the
Global State Cell.
This configuration reads
"trigger if any of these events
occur."
An event sequence. This reads "If a primitive
is followed by an error, then trigger."
