Need to compare two datagrids

Hi Skip,
Following Phil's suggestion, I think you could do this using the filter
command, something like this:

put the dgText of group dg1 into tdg1Text
put the dgText of group dg2 into tdg2Text
set the itemdelimiter to tab
repeat for each line rLine in tdg1Text
   filter lines of tdg2Text with item 1 of of rLine into tTemp
   if tTemp is empty then
      put rline & return after tdg4Text
   else
      put rLine & return after tdg3Text
   end if
end repeat

set the dgText of group dg3 to tdg3Text
set the dgText of group dg4 to tdg4Text

Haven't tested that and I'm not sure how efficient it would be if there are
a large number of rows in dg1 and/or dg2 but it's a starting point.  Oh,
and you'd need to be on whatever version of LC the new filter command
syntax was introduced in (6.1?)
