Session
The 370 Processor Control Session
is
a general purpose
debug facility similar to the debug facilities found
on
the
operator console of other
IBM

as
one of several
concurrent sessions.
It
can
be
entered from any other

The
370
Processor Control Session
is
a full screen utility
designed to increase the productivity of debugging sessions
through the use of such features as full screen register and
storage editing. There are no commands to remember. All
actions are communicated to the
370
Processor Control
utility through the use of function keys. The description
of
these keys
is
on
the screen in case you should forget them
