>>>I analyze the stack. But the method INIT is not in the aProgStack. This is the sample code how I scan through the stack:

>>>ASTACKINFO(aProgStack)
>>>FOR iEle = 1 TO ALEN( aProgStack, 1 )

>>You got the answer to your question. I just want to add that when I want to know all the events that fire and the order, I use the Event Tracker. For debugging, I often add DEBUGOUT commands in methods to track where I am and what's going on.
