Thanks, Barb.

Wow. This is new to me, but I'm trying...
I've read the "Getting started with User Defined Functions",
created the "personal.xls" file,
entered that text (from "Function..." down to "End Function") starting
in A1,
saved that personal.xls file in the XLSTART directory,
opened my datafile.xls,
inserted a column 1 and put "=personal.xls!findpattern(B1:Z1,"@")" in
A1,
and it says #NAME?.

Help, please?

Thanks very much, in advance, people.
