I am going to say yes.  I am trying to figure out a way of replacing nan
values with zero.  This is what I tried.

test=test1,UNKN,EQ,test1,0,IF

test=test1,test1,0,IF

test=test1,UN,test1,0,IF

I thought the last one would work but to no avail.  The problem I am
having is I have to add to values together but it is possiable for either
one of these values to be nan.

Any help?
