Hi Cavin,

Not sure, that I understand, what are you looking for, but if you want to check the whole file record by record, use scan ... endscan, e.g.

local lnAge
if not used('MyTable')
  use MyTable in 0
endif
select myTable
scan
 if age<>lnAge
   flag=.f. && What is a flag, BTW, field name?
 endif
endscan
