statement is printed after the answer is printed.

</TT></PRE><P>When <em>time</em> is first turned on, the time since the beginnin
g of the
REDUCE session is printed. After that, the time used in computation,
(usually in milliseconds, though this is system dependent) is printed after
the results of each command. Idle time or time spent typing in commands is
not counted. If <em>time</em> is turned off, the first reading after it is
turned on again gives the time elapsed since it was turned off. The time
printed is CPU or wall clock time, depending on the system.
