Many thanks, Juan, I understand the situation now.

The number in A1 is stored as text. When you edit the cell and hit enter,
you force Excel to change it to a real number.

I have an what appears to be a five digit integer in cell "A1" which
has
a
very strange property. If I type the same five digits into cell "A2" and
then in a cell "A3" type the function =if(Range("A1") =
Range("A2"),"Yes","no") the result is "no". If I then double click
cell
"A1" (as if I wanted to edit) and hit the enter key, the function
value
magically changes to "yes". The strange integer was copied from the zip
code
field of an address file.

Can anyone please tell me what's going on?
