I believe the function you are looking for is match() instead of find().
Find looks for the first argument in each element of the second argument,
while match looks for the first argument as occurring as a slice in the
second.

Going back to your original example, I would rewrite it as:

object data
integer datafound
sequence datatofind

datafound = 0 -- false

while not datafound do
       data = gets( dctstrfile )
       if atom( data ) then
           exit  -- end-of-file
       end if
       datafound = match( datatofind, data )
end while
