Here is one solution (I think) with only one loop and I am also using the < pre > tags for the first time ;)

for i = 1 to alen(myarray)
  if ascan(myarray, X - myarray(i)) > 0
    return myarray(i), myarray(ascan(myarray, X - myarray(i)))
  endi
next i

No cigar again. ASCAN traverses (loops through) the array to locate the desired element so your solution still involves a double loop.
