As I think more about how to best do this, I wonder if/how python
script would import File A with search values, File B to be searched,
and write each full line containing any of those results to File C.
The code could be set to look for the same input file (A, with the
search values), and the same filename to write to (File C), thus
leaving only the prompt for the file to be searched (File B).
The user would be responsible for listing the search term variables
into File A prior to running the script.
Is this simple enough?
