... while waiting for Jef to respond further ..

Perhaps you could drop me a line or 2 here what was it about the non-array
formulas approach suggested in my response which failed to meet the specs
you posted ? Or, which part of the response was not up to your expectations
? Just wanted a closure to this exchange of views before the thread fades
away .. Thanks.
