Hi David,
The regex actually returns the string within the parens so to get the char
position of the parens, the function should return tStart-1 and tEnd+1
which would be 1 and 6 in your example, which I think is what you want?

Glad your function works though, you should probably go with it if it feels
more comfortable.  Your situation was a challenge for me to find a way to
do it with a regex :-)
