watch [on|off] Default: off
_________________________________________________________________
The 'watch' command displays the current software stopwatch
values, with min and max readings for each. This facility allows
a programmer to measure the execution time of critical sections
of code with microsecond resolution.
This command is supported only on the IBM PC, and the meaning of
each stopwatch value depends on where the calls have been
inserted for test purposes; the distribution copy of NOS usually
has no stopwatch calls.
[With some machines it may be essential to keep 'watch' turned
off, as there are unwanted side effects if it is turned on. For
example, it makes the PC emulator in the Archimedes machine
beep!].
