THE CONTROLS
General As
a
Terminal
operator,
understanding the Terminal
controls
is
an
important
part of
your
job.
Of
course,
if
you
are
not
familiar with
computer
terminals, the
purpose and
usage of
some
of the controls
may
be unfamiliar
at
first.
But,
as
you
use the Terminal your understanding
of
Terminal
controls
and
operation
will
increase proportionately.
NOTE
Because
of
the variety
of
systems, the purposes of
some
controls
will
vary
from system
to system.
Purpose
of Controls
Even though
the
Terminal Keyboard
looks
like a
typewriter keyboard,
its
use
is
quite different.
Typewriter keys and
controls provide
a
convenient
means
of writing, with functions designed
toward
outputting
printed
material
on
a
piece of paper.
The
Terminal keyboard
and
controls are
designed
to
manipulate computer-based
data.
THE KEYBOARD'S
PRIMARY FUNCTION
IS
TO ACT
AS
A SOURCE
OF
DATA
FOR THE
COMPUTER.
The
screen (or
display— both words
are used interchangeably
throughout
this
manual)
is
a
convenient
means
of recording, for operator
convenience, the Terminal/computer
conversation. Editing functions and
display
formatting
are
simply Terminal
features that provide
more
efficient
Terminal/computer communications.
So,
even though
for
most
operations
the
keyboard
appears to be "talking" with only
the screen, the
result (or
end
result)
of
keyboard
data manipulation
is
directed
toward the computer.
Keeping
this in
mind
will
help to better
understand
the use of the
controls.
