 For each signal there is a flag and a trap enabler.  When a signal is
-encountered, its flag is incremented from zero and, then, if the trap enabler is
+encountered, its flag is set to one, then, if the trap enabler is
 set to one, an exception is raised.  Flags are sticky, so the user needs to
 reset them before monitoring a calculation.

 computation, flags may be checked for informational purposes (for instance, to
 determine whether a computation was exact). After checking the flags, be sure to
 clear all flags before starting the next computation.
