Oh.., now you tell us! Any other *very important details* like this we need
to know?


Hi Gary! I've been busy with some stuff, but I'm going to test your
latest code soon and see how it works.

Regarding the *very important details*, I can explain that. Here goes:

I believe I did provide sufficient details in my earlier posts. In
my first post titled "Tricky regular expression", I explained that I was
looking for "the first set of whitespaces that occur in the line".

Also, I figured that once you provided any solution,I could easily tailor
it to work with files containing one input line or multiple lines.

So, I'm going to test your code soon and see how it goes. Thanks again
for your help!
