why is the INDIRECT function volatile?

[Guest]

I was reading this white paper on performance optimization in XL 2007,
http://msdn2.microsoft.com/en-us/library/aa730921.aspx , and it indicated
that the function INDIRECT is volatile. I can't figure out why that function
would be volatile.

Thoughts?

That probably is because Excel bases dependencies on cell references. And a text (like "B1") is not seen as a cell reference.
So if A1 contains "B1" and C1 is =Indirect(A1) and if you change the value B1, C1 would not be recalculated if Indirect wasn't
volatile.

That makes sense, thanks.
