of legal responses are surrounded by (). "/HELP" may be typed

Charge numbers are set in the monitor by the LOGIN UUO for
accounting purposes. The TOPS-10 monitor, however, makes no use
of the charge number. Therefore, the format was never defined.
Usually, it is a sixbit number.

MAP, the page mapping subroutine package, has the ability to
keep track of it's own runtime. The accumulated runtime is made
available to WHO for displaying the mapper performance when the
/MPERFORMANCE switch is used. Answering "YES" to this question
will cause two RUNTIM UUOs to be executed on each call to the
mapper. Doing this could possibly cause excessive overhead.
