I have tried this again: I entered A4 as =A2="": I get TRUE, not FALSE:
you get FALSE. I am on 184.108.40.206 on Vista.

I use Libreoffice to process files over which I have no control. These are

LO (220.127.116.11 on Vista) seems to handle some values in cells inconsistently
... open a new spreadsheet:
set A2 =CHAR(127)
set A3 =A1=A2
set A4 =A2=""
A3 contains FALSE
A4 contains TRUE
Surely A3 and A4 should be the same, since A1 contains the null string.
When I do this, I get FALSE in cell A4 — but I'm not sure what is
being done here. I'm not sure what A1 contains if nothing has been
entered; A2 is the delete control character; A3 is basically asking if
the empty cell is equal to the delete control character (obviously
not, hence FALSE); and A4 is asking if the delete control character is
equal to nothing entered (obviously not, hence FALSE).
Did you mean for the formula in A4 to be »=A1=""« ??? because that
should be TRUE.
No, I mean =A2="".
The help function for the =CHAR(n) function says the value is from 1
to 255; using values above 255 produces Err:502. The null value would
be =CHAR(0), and even though this does not produce an error message,
Calc attempts to interpret it as something — which isn't null.
If I've misunderstood, please clarify.
It appears that LO is behaving differently on our two systems.
