Hi Boleslav,
On Tuesday, February 4, 2003, 9:38:14 AM, you wrote:
BB> op: either x < 0 [:+][:-]

op: either x < 0 [:add] [:subtract]
a: op a 1
But then, I'd write it as:
a: a + sign? - x
(Well, there's a little difference, this does nothing if x is
zero, while yours subtracts 1.)
Regards,
Gabriele.
