About your question, you may declare a PUBLIC variable called myrequest, then:
myrequest = myagent.characters("Genie").SPEAK("HELLO")

MyAGent.RequestComplete Event

DO WHATEVER....
ENDIF
ENDIF

There may other ways to do it, but I can't remember.... check out the home pages above......

Hope It Helps
