If I have a cell that contains numeric & alpha data how do I extract just the
alpha part? All my data begins with the letter "F". How can I pull just the
"F" out of the cell?

Example:

F00143

Not all the cells have the same number of characters in it. They might have
5 numbers after it, or 4, or 3. I just want to extract the beginning
character since it's the alpha portion.
