Hmmm, I never noticed that but you are right.  I suppose it's related to the
fact that in the language definition the `-' is considered an operator and
not part of a number.

To get around your problem, there are two possible approaches:

1) With the latest o2c, there is a new module called FIn which can read
   input from a file.  It supports signed integers.

2) You would be forced to input a string and then convert it to an integer
   using the IntStr module.
