Hi Anne,

This is not true for single-letter names. In the past I have
successfully named cells as "a" and "b" (w/o the quotes). It is
particularly nice as instructive technique when I want to use Excel for
demo of linear function behavior. Afterall, a cell's original name
cannot be letter only, since we need the column number as well, so no
conflict there...

And as I was writing just this I realized... and tested... It conflicts
with the R1C1 notation. So, similarly the leter "r" and the string "rc"
cannot be used as names. All other single letters can (probably...)

Regards,
Kostis
