Thanks guys for the response.

My application defaults to set exact off. This routine that does the comparison can be called from many places in my application. I was wondering your opinions on whether it would be more efficient to do a set exact on do my comparison with inlist() and then set it back off....or if I should use the $ command? Keeping in mind that this routine can be called millions of times

Thank you,
Paul
