Stack Trace Function

[Len Morgan]

In trying to debug a rather complex application, I'm wondering if there 
is some sort of "stack trace" fuction (like there is in Tcl/Tk) so that 
when a message is sent, I can see the calling sequence that got me there?

What's happening is that I have a message that clears a group when the 
group is selected (kind of like a tabbed group) and also whenever a new 
record is read while the group is being already being displayed (I don't 
want to leave data from a prior record in a field that might not be used 
in the current record).  When I select a new record, the fields are 
getting cleared 2 or 3 times (the screen blinks) and I can't find all 
the places that are calling that routine (and in what order).

It doesn't have to be fancy, just some what to see who's calling who, when.
