(there are very few). The
370
Processor Control Session
was also designed
to
be
keystroke efficient.
That
is, actions
you request require a minimum
amount
of
keystrokes.
The
370
Processor Control screen is divided into four areas
as indicated in Figure B-1 .
The
documentation
that
follows
references these areas. Figure B-2 shows
the
actual layout
of
the screen.
