Jim, I hope you didn't take my little experiment as some kind of one-
upmanship - it certainly wasn't intended as such.
I was simply interested to see, in this example of removing double-
spaces, how great the difference was between the more flexible regex
approach, and the more specific "replace" approach.
As you suggest, with blocks of text of a few thousand characters,
there's clearly little benefit to be had from chasing a millisecond
or two, but with larger blocks, or with batches of blocks, it might
well be useful to know that one method is ten times faster than another.
Apologies if misconstrued,
Mark

Ooooops I clicked 'send' too quickly... That should read:
Approximation:
A text block containing 1700 characters, 50% of which were spaces,
would
take about
*2 milliseconds*
to use ReplaceText pattern searching,
which is 10 times slower than the Replace technique you programmed.

Interesting, Mark. Good example. [see code below in original post]
So 20 milliseconds div 10,000 space runs
= 2.0 x 10^-2 seconds div 1.0 x 10^4 = 2.0 x 10^-6 seconds
