LQ etiquette prefers that you post the solution, not just "I found it". As much as you needed help, other might need that as well and might not able to find it.

So thank you for editing your post and briefly indicating what you found.

event = $1
level = $4

if (level == "AGT" && event == "s" )

this is in trace file of ns2

Personally I would have to say I do not see how the final solution is related to the original question??

There is no mention of variables in original nor any if context.

In future it may help if you provide a full question, ie. what is required, what data is being worked on, what is the desired output, perhaps some references to where you retrieved the unknown code.
And finally, when you have a solution, relate it to the original question so others may learn from it as well.

And, for anyone who finds this looking for an answer to the first question:
$0 ~/^s.* AGT/ is a regular expression test statement, comparing the input line ($0) with the expression "^s.* AGT", which means "A string starting with a lower-case "s", followed by zero or more characters followed by a blank and the upper-case string "AGT"
