Tom,

Instead of typing in the formula and pressing <Enter, you need to type the
formula in, hold down the <Ctrl key, hold down the <Shift key, and while
those two keys are held down, press the <Enter key. This enters the
formula as an array formula, which is a special formula type that evaluates
each cell in the range on a cell by cell basis, rather than all at once.

If you cannot get the formulas to work, I will send you a sample workbook
with the formulas working, if you post your email address or contact me
privately.

Skyscan,

Array enter each of these (enter using Ctrl-Shift-Enter)

First filled cell of row 2:
=ADDRESS(ROW(2:2),MIN(IF(2:2<"",COLUMN(2:2),256)) )

Last filled cell of row 2:
=ADDRESS(ROW(2:2),MAX(IF(2:2<"",COLUMN(2:2),0)))

Hello!

I have data in a single row array. The data is not contiguous such
that
there are holes in the data. Several cells may be blank in the first
few
cells, in the middle cells, or in the last cells. I need to identify
which
cell is the one where the data begins. In addition, I need to
identify which
cell is the one where the data ends. It is not necessary to locate
"holes"
in the data set. I would like to use functions only to identify
these first
and last cells.

Thank you very much!!

Tom
