I suspected as much. but thought SURELY someone
reverse-engineered the Call Stack Dialog box...

I also dredged up some memories from back in
my Focus/Fortran/C++ days, and I distinctly remember
interrogating the stack... Then I remembered,
I BUILT the stack...

Looking around, it looks like that's what MS recommends.
Creating a Class object and using push/pop to manage the stack.

Oh well... i thought I might've had a work-around...
Guess not..
