It's the contents of an array that I'm looking for dups in. In this particular case, the records each come from separate files.

I was thinking of doing something like the following

code:

i = 0
j = 0
last = 0
while i < last
  j = i
  while j < last
    if array[i] = array[j]
      exit loop
    endif
  j = j + 1
  loop
i = i + 1
loop
