Hi Ly,

I didn't suppose that you needed to cut back the depth of nesting; it seemed that the nesting structure is intrinsic to the task.
But if it works, then okay.

The point to know is that when a segment of code is inside a loop that gets repeated many times, it should be as time-efficient as possible. Plus, reading/writing files is much slower than computations and memory-read/write operations.

I'm glad that its working well for you now.

Hi David,

Thank you for your quick and very thorough response.
Thanks to your suggestions, I did go back and found a way to speed up
the program by rewriting the 4 ado files (which in turns allow me to
cut back on the nested loops).

Thanks so so much.
