Note that there is some overlap in the way these counters can be used. For example, in
the simple case of a single event leading to a single action, it makes no difference
whether you specify the event to require five repeats before triggering the action, or the
action to require five occurrences before it acts.
However, in the case of combined events and/or actions, the separate counters provide
flexibility in designing test cases. For example, consider the case where Event_1 OR
Event_2 leads to Action. If Event_1 has a counter of 5, then the Action triggers either
when Event_1 has repeated five times or when Event_2 happens the first time,
whichever occurs first.
But if the event counters are set to 1 and the Action counter is set to 5, then the Action
happens after five occurrences of EITHER Event_1 or Event_2.
4.8.3 Capturing a Data DWORD
InFusion provides the ability to capture individual data DWORDs and provides four
different registers to store captured DWORDs (DWORD #0, #1, #2 and #3).
To capture a data DWORD, select Capture Data DWORD from the Action Properties
screen, as shown below. Select the register to be used to store the DWORD from the
drop‐down menu under the Capture Register property.

4.8.4 Using Captured Data DWORDs
Captured data DWORDs can be used in creating events for data that match the captured
DWORD(s), or in creating actions to substitute the captured DWORD(s) into the data
stream.
