Sorry I'm this late. Maybe too late.
I suppose there's not the same number of records in the two tables(it might be very normal for you but you didn't specify it). If you want to check in Table2 only those which correspond to a recort in Table1 try this :

select Table1
scan
scatter to xxx memo
if seek(...some code..., "Table2")
select Table2
scatter to yyy memo
for iii = 1 to number_of_fields
if xxx(iii)=yyy(iii)
* bring in Table2 the array created with Table1
gather from xxx memo
* exits for
exit
endif
endfor
endif
select Table1
endscan
