I am assuming that line is declared as a sequence. gets() can return a 
sequence, which is the line, or -1 at the end of the file. In this case, it 
is returning -1, which cannot be assigned to a sequence. The solution is to 
declare line as an object, and then check if it is an atom, in which case, 
you would exit the loop. This is already done in the code, though.
