Additionally...were I to use indexOf() and the user entered test instead
of testing, I'd see a incorrect true response. That's what drove me to try
a regular expression to find a perfect match.

I'm very interested in why you believe my argument to be invalid. (Please)

I was wrong! Thanks...you got me thinking (for a change it seems)

The answer is so simple, I'm embarrassed having asked the question. :-)

firstString = document.form.elements["firstString"].value; //'Mary Smith'
testString = document.form.elements["testString"].value;
//Mary Smith-00003.img

adjName = testString.indexOf("-00");
endName = imageName0.substr(0,adjName);
testNames = endName.indexOf(firstString);
if (testNames != -1 && firstString == endName)  {
	alert("Identical")
}

From here, it's a simple task of identifying why the names are not
identical and alerting the user. With appropriate validation on
firstString input, I can filter out erroneous firstString inputs, e.g.,
double spaces. I have no control on validating testString, except the
knowledge its form is 'userinput-nnnnnm.img.'

The word doh! comes to my mind. 

Thank you.
