Hi -
My idea of sending to a file and counting the lines is essentially the same
as several other suggestions:
1) Charles King suggested outputting to a array and then checking the
contents of the array, and
2) Pat Richards suggested adding a counter, which would have exactly the

Without actually trying it, the first thing that comes to mind is to
insert a counter in your while loop. If, at the conclusion of the loop,
it only == 2, then you're likely in an empty directory (you'd have the .
And .. To give you the two).
Make sense?

simply test the number of lines in the ASCII file to see if there is a line
for a file, and based on that return either the report you have in the file
or your text string.
Hope I'm clear on this. This is how I
