PAl,
PA2, alld PA3 Keys
PAl,
PA2, and PA3 are Program Access (PA) keys, and
they
perform the func-
tion
that
their name implies;
that
is, they provide a means
of
signaling the program
or communicating with it. While
your
display station
is
signaling the program, the
Do
Not
Enter - Time (
)(
):.
) message appears in the Operator Information
Area, disabling
your
keyboard. Most programs, when replying to these keys,
turn
off
the Time message. However, this
is
up
to
the program. The program
that
is
operating in
the
host
system
at
the time also determines
how
these keys are used.
If
you
are
not
familiar with the use
of
the PA keys, ask the appropriate person in
your organization
about
the use
of
the PA keys or refer
to
the appropriate user's
program guide.
