I have a formula that I want to use to generate (depending on the situation)
a blank value. I thought a null string ("") was equivalent to a blank but
that doesn't seem to be the case.

Here's my example:

Contents of cell A2: =IF(A1=0,"",A1)

I want to be able to do a a Copy...Paste Special...Values with cell A2 and
have it copy a blank to the destination cell if cell A1 contains a zero.

In the above example, if I copy the value of cell A2 into cell A3, the
ISBLANK function tells me that cell A3 is not blank (i.e., it returns FALSE).
If I use the LEN string function, it returns a zero (i.e., a string of no
length).

Can someone explain to me the logic behind this? Does someone know what I
can enter into the IF function above so that it return a blank value (at
least it's blank when the value is copied to another cell)?

Thanks for any and all help.
