Hi Jay,

On the way home I figured this out. I will need bunch of local variables, so in my scan loop I would do something like:

lcccrctown=ccode+rcode+town
lcMinDate=record_fm
etc
scan &lcFor
  if ccode+rcode+town = lcccrctown
      lcMinDate=min(record_fm,lcMinDate)
      ...
   else
      replace .. in FilingDate 
      lcMinDate = record_fm
      lcccrctown=ccode+rcode+town
   endif
endscan

This way I would not need to use replace on each scan, I can properly work with Notes field, etc.
