Good observations and catches! I was cleaning up unnecessary lines
within the code, which I have found to work. Evidently, I
inadvertently deleted the declaration of the i integer variable, like
Int i
Regarding setting the COM object to Null, it is not supposed to be
necessary, and evidence supports this, yet there is no harm to it, and it
may minimize the risk of memory leaks.
