I've been trying different text functions for a spreadsheet I'm working on.
Came across the "T" function, but can't get it to work. (Isn't this a
terrible name for a function, a single letter?)

If I simply apply it alone, as in =t(B7) in cell C7, it seems to behave as
described. If B7 is alpha, T returns the alpha string. It B7 is a number,
it returns a blank. Ok.

But if I put a LEFT function inside it to use it to determine if the
leftmost character in a string is alpha or numeric, it goes kablooie!

I.e., I put =T(LEFT(B7,1)) in Cell C7. If I put abc in cell B7, it returns
the "a". Great. but if I put 222 in cell B7, it returns a 2! It should be
blank since the 2 is numeric. So why does it return 2?

I was going to wrap an IF statement around all this to determine if a
string starts with a alpha or a numeric character, but this obviously wont'
work. Is this Excel function just broken?
